Question

This circle has a radius of 12 millimeters and is divided into 8 equal sections. In terms of pi,

Answer 1

Answer:

        A = 18π mm²

Step-by-step explanation:

Area of a circle: $A_\circ =\pi r^2$ where r is a radius of this circle

8 equal section means area of one is:  $A=\dfrac{\pi r^2}{8\ }$

r = 12 mm

$A=\dfrac{\pi\cdot 12^2}{8\ }=\dfrac{144\pi}{8}=18\pi$
