Area= pi × radius2

Area= 3.14 × (4.5 in2)

Area= 3.14 × 20.25

Area= 63.585 in2

The answer is 63.585. You would find this answer by doing this:

20.25

x3.14

_______

8100

20250

+607500

_______

635850

Then you would take the zero off the end.

How calculate area circle?

The formula for finding the area of a circle is pi * r², where pi = 3.14; * = multiply; r = 1/2 of the diameter; and ² = squared (multiplied by itself). An example of how to calculate the area of a circle with a 6 inch diameter (3 inch radius): a = Pi * r² a = 3.14 * 3² a = 3.14 * 9 a = 28.26


What is the area of a 12 inch and a 9 inch circle?

The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. For a 12-inch circle, the radius is half of the diameter, so the radius is 6 inches. Therefore, the area of the 12-inch circle is A = π(6)^2 = 36π square inches. Similarly, for a 9-inch circle, the radius is 4.5 inches, so the area of the 9-inch circle is A = π(4.5)^2 = 20.25π square inches.


What is the diameter of a 9 inch circumference?

To find the diameter of a circle with a 9-inch circumference, you can use the formula for circumference: C = πd, where C is the circumference and d is the diameter. In this case, C = 9 inches. Rearranging the formula to solve for the diameter, you get d = C / π. Substituting in the known values, the diameter of a circle with a 9-inch circumference is approximately 2.87 inches.
