Question

circumference and area of circ find the area of each. use your calculat 1) 12 in

Explanation:

Step1: Recall area formula

The formula for the area of a circle is $A = \pi r^{2}$, where $r$ is the radius of the circle.

Step2: Identify the radius

From the problem, the diameter $d = 12$ in. Since $r=\frac{d}{2}$, then $r = 6$ in.

Step3: Calculate the area

Substitute $r = 6$ into the area formula: $A=\pi\times(6)^{2}=36\pi\approx36\times3.14 = 113.04$ in².

Answer:

$113.04$ in²
