Find the area of the following circle.
r = 9 yd.
r=9 yd
A = pi * r^2
A = 3.14 * 81
A = 253.34 square yards
this make me so mad
To find the area of a circle, you can use the formula:
Area = π * r^2
In this case, the radius (r) is given as 9 yards.
First, square the radius:
r^2 = 9^2 = 81
Next, multiply the squared radius by π (pi):
Area = π * 81
Finally, calculate the area using an approximate value of π. Let's use 3.14:
Area ≈ 3.14 * 81
Area ≈ 254.34 square yards
Therefore, the approximate area of the circle with a radius of 9 yards is 254.34 square yards.
