what is area of a circle?
The area of a circle is calculated using the formula:
Area=Ļ
where Ļ (pi) is a mathematical constant approximately equal to 3.14159, and r 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:
Given a 10-inch diameter circle, the radius (ā) would be 210ā=5 inches.
Now, substitute this radius into the formula:
So, the area of a circle with a 10-inch diameter is 25Ļ square inches. If you want a numerical approximation, you can use Ļā3.14 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:
Given a 20-inch diameter circle, the radius (ā) would be 220ā=10 inches.
Now, substitute this radius into the formula:
So, the area of a circle with a 20-inch diameter is 100Ļ square inches. If you want a numerical approximation, you can use Ļā3.14 to find the approximate area.
formula for finding the area of a circle
The formula for finding the area (A) of a circle is given by:
where:
- Ļ (pi) is a mathematical constant approximately equal to 3.14159.
- r is the radius of the circle.
Alternatively, you can use the diameter (D) of the circle to find the area using the formula:
Here, D is the diameter of the circle, and ā is the radius.
formula for circumference of a circle using radius
The formula for finding the circumference (C) of a circle using its radius (r) is given by:
C=2Ļr
where:
- Ļ (pi) is a mathematical constant approximately equal to 3.14159.
- r 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 Ļ.
1 diameter circle area
If you have a circle with a diameter of 1 unit, the radius (r) would be half of the diameter, so
The formula for the area (A) of a circle is:
Substitute the radius into the formula:
ā
So, the area of a circle with a diameter of 1 unit is ā square units. If you want a numerical approximation, you can use Ļā3.14 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:
ā
where:
- A is the area of the circle,
- C is the circumference of the circle, and
- Ļ is a mathematical constant approximately equal to 3.14159.
If you have a circle with a circumference of 10 inches, you can substitute C=10 into the formula:
ā
ā
So, the area of a circle with a circumference of 10 inches is ā square inches.
12 inch diameter circle area
If you have a circle with a diameter of 12 inches, the radius (r) would be half of the diameter, so 6 inches.
The formula for the area (A) of a circle is:
Substitute the radius into the formula:
So, the area of a circle with a 12-inch diameter is 36Ļ square inches. If you want a numerical approximation, you can use Ļā3.14 to find the approximate area.
14 inch diameter circle area
If you have a circle with a diameter of 14 inches, the radius (r) would be half of the diameter, so 7 inches.
The formula for the area (A) of a circle is:
Substitute the radius into the formula:
So, the area of a circle with a 14-inch diameter is 49Ļ square inches. If you want a numerical approximation, you can use Ļā3.14 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 (A) of a circle:
Substitute the radius into the formula:
So, the area of a circle with a radius of 14 inches is 196Ļ square inches. If you want a numerical approximation, you can use Ļā3.14 to find the approximate area.
15cm diameter circle area
If you have a circle with a diameter of 15 centimeters, the radius (r) would be half of the diameter, sorā=7.5 centimeters.
The formula for the area (A) of a circle is:
Substitute the radius into the formula:
So, the area of a circle with a 15-centimeter diameter is 56.25Ļ square centimeters. If you want a numerical approximation, you can use Ļā3.14 to find the approximate area.
16 inch diameter circle area
If you have a circle with a diameter of 16 inches, the radius (r) would be half of the diameter, so ā=8 inches.
The formula for the area (A) of a circle is:
Substitute the radius into the formula:
So, the area of a circle with a 16-inch diameter is 64Ļ square inches. If you want a numerical approximation, you can use Ļā3.14 to find the approximate area.
