Answer:
236.25
Step-by-step explanation:
To get the area of the shaded portion, add up all the areas of the 3 quadrants
First, find the area of one quadrant
Area of a quadrant = 1/4 π
π = 3.14
Radius, r = 10 cm
A = 1/4 *3.14 *
A = 1/4 *3.14 * 100
A = 1/4 *314
A = 78.75
Now, multiply by 3
3 * 78.75
= 236.25
