The area of a circle is pi times the radius squared (A = π r²).
Multiple 15 by 6, the answer is 90 square cm
Sum of two interiors=exterior




Answer: A=351.68 cm²
Step-by-step explanation:

Area of Circle



Area of inner (white) circle



Now that we have the area to the circle and inner circle, we would subtract to find the area of the shaded region.
