Question

a circle has a radius of 12 inches. find the area of the circle. you can use 3.14 as an approximation for π. a = π·12² the area of the circle is about square inches.

Explanation:

Step1: Recall area formula

The formula for the area of a circle is $A = \pi r^{2}$, where $r$ is the radius. Here $r = 12$ inches and we use $\pi\approx3.14$.

Step2: Substitute values

Substitute $r = 12$ into the formula: $A=3.14\times12^{2}$.

Step3: Calculate $12^{2}$

$12^{2}=12\times12 = 144$.

Step4: Multiply by 3.14

$A=3.14\times144 = 452.16$.

Answer:

452.16
