grigory [225]
12 + 0.15m = 10 + 0.25m
0.15m - 0.25m = 10 - 12

2. The logo shown below was created by splitting a circle into 6 equal sections. Raphael is creating a stage-sized version of th
andrew11 [14]
From the shaded diagram, Raphael will need 3 of the 6 equal portions, or exactly 1/2 of the area of the circle. Given a radius of 12 ft, knowing that the area of any given circle is \pi r^2, and knowing that the area of the fabric needs to be half of the total area, we can set up the equation for the area of the fabric A:

A= \frac{1}{2}\pi (12)^2

Simplifying, we find that the area of the fabric is exactly

\frac{1}{2} \pi (144)= \frac{144}{2} \pi=72\pi ft.² Using the approximation of 3.14 for π, we get an area of approximately 72(3.14)=226.08 ft² of fabric.
