Question

a circle has a radius of 12 inches. find the approximate area of the circle. use the formula a = πr² to write an equation that would help you find the area of the circle.

Explanation:

Step1: Identify the radius value

The radius $r = 12$ inches.

Step2: Apply the area - formula for a circle

The formula for the area of a circle is $A=\pi r^{2}$. Substitute $r = 12$ into the formula: $A=\pi\times(12)^{2}=\pi\times144 = 144\pi$.

Answer:

$144\pi$
