Question

Use the formula for the area of a circle to find the area of the bulls eye.

Answer 1

ANSWER

C. 452.39 mm²

EXPLANATION

The formula for the area of a circle is,

$A=\pi r^2$

The radius, r, of the bull's eye is 12 mm, so its area is,

$A=\pi\cdot12^2mm^2\approx452.39mm^2$

Hence, the area of the bull's eye is 452.39 mm².
