## what is area of a circle?

The area of a circle is calculated using the formula:

where (pi) is a mathematical constant approximately equal to 3.14159, and is the radius of the circle. The formula represents the space enclosed by the circle in square units.

## 10 inch diameter circle area

To calculate the area of a circle, you can use the formula:

$\text{Area}=Ã—{\left(\frac{\text{Diameter}}{2}\right)}^{2}$

Given a 10-inch diameter circle, the radius ($\frac{\text{Diameter}}{2}$) would be $\frac{10}{2}=5$ inches.

Now, substitute this radius into the formula:

$\text{Area}=Ã—\left(5{\right)}^{2}$

$\text{Area}=Ã—25$

So, the area of a circle with a 10-inch diameter is square inches. If you want a numerical approximation, you can use to find the approximate area.

## 20 inch diameter circle area

To calculate the area of a circle with a diameter of 20 inches, you can use the formula:

$\text{Area}=Ã—{\left(\frac{\text{Diameter}}{2}\right)}^{2}$

Given a 20-inch diameter circle, the radius ($\frac{\text{Diameter}}{2}$) would be $\frac{20}{2}=10$ inches.

Now, substitute this radius into the formula:

$\text{Area}=Ã—\left(10{\right)}^{2}$

$\text{Area}=Ã—100$

So, the area of a circle with a 20-inch diameter is square inches. If you want a numerical approximation, you can use to find the approximate area.

## formula for finding the area of a circle

The formula for finding the area () of a circle is given by:

where:

• (pi) is a mathematical constant approximately equal to 3.14159.
• is the radius of the circle.

Alternatively, you can use the diameter () of the circle to find the area using the formula:

Here, is the diameter of the circle, and $\frac{}{2}$ is the radius.

## formula for circumference of a circle using radius

The formula for finding the circumference () of a circle using its radius () is given by:

where:

• (pi) is a mathematical constant approximately equal to 3.14159.
• is the radius of the circle.

So, to calculate the circumference of a circle, you simply multiply the radius by 2 and then multiply the result by .

## 1 diameter circle area

If you have a circle with a diameter of 1 unit, the radius () would be half of the diameter, so $=\frac{1}{2}$

The formula for the area () of a circle is:

Substitute the radius into the formula:

$={\left(\frac{1}{2}\right)}^{2}$

$=Ã—\frac{1}{4}$

So, the area of a circle with a diameter of 1 unit is $\frac{}{4}$ square units. If you want a numerical approximation, you can use to find the approximate area.

## 10 inch circle area

To find the area of a circle when you know the circumference, you can use the following formula:

$=\frac{{}^{2}}{4}$

where:

• is the area of the circle,
• is the circumference of the circle, and
• is a mathematical constant approximately equal to 3.14159.

If you have a circle with a circumference of 10 inches, you can substitute into the formula:

$=\frac{1{0}^{2}}{4}$

$=\frac{100}{4}$

So, the area of a circle with a circumference of 10 inches is $\frac{100}{4}$ square inches.

## 12 inch diameter circle area

If you have a circle with a diameter of 12 inches, the radius () would be half of the diameter, so $=\frac{12}{2}=$ inches.

The formula for the area () of a circle is:

$={}^{2}$

Substitute the radius into the formula:

$=Ã—{6}^{2}$

$=Ã—36$

So, the area of a circle with a 12-inch diameter is square inches. If you want a numerical approximation, you can use to find the approximate area.

## 14 inch diameter circle area

If you have a circle with a diameter of 14 inches, the radius () would be half of the diameter, so $=\frac{14}{2}=$ inches.

The formula for the area () of a circle is:

Substitute the radius into the formula:

$=Ã—{7}^{2}$

$=Ã—49$

So, the area of a circle with a 14-inch diameter is square inches. If you want a numerical approximation, you can use to find the approximate area.

## 14 inch radius of a circle area

If you have a circle with a radius of 14 inches, you can use the formula for the area () of a circle:

$={}^{2}$

Substitute the radius into the formula:

$=Ã—1{4}^{2}$

$=Ã—196$

So, the area of a circle with a radius of 14 inches is square inches. If you want a numerical approximation, you can use to find the approximate area.

## 15cm diameter circle area

If you have a circle with a diameter of 15 centimeters, the radius () would be half of the diameter, so$=\frac{15}{2}$ centimeters.

The formula for the area () of a circle is:

Substitute the radius into the formula:

$=Ã—\left(7.5{\right)}^{2}$

$=Ã—56.25$

So, the area of a circle with a 15-centimeter diameter is square centimeters. If you want a numerical approximation, you can use to find the approximate area.

## 16 inch diameter circle area

If you have a circle with a diameter of 16 inches, the radius () would be half of the diameter, so $=\frac{16}{2}$ inches.

The formula for the area () of a circle is:

Substitute the radius into the formula:

$=Ã—{8}^{2}$

$=Ã—64$

So, the area of a circle with a 16-inch diameter is square inches. If you want a numerical approximation, you can use to find the approximate area.
