Question

Someone help I have no idea how to do this, it would help if I could get a step by step

Answer 1

Answer: x=3

Explanation:

shaded part is 5/6 of the full circle, so just make an equation.

5/6 pi r^2(formula to find area)=15/2 pi(area given)

cancel out pi and simplify

r^2=9

r=+-3 but cant be negative so r=3
