Answer:

236.25  [tex]cm^{2}[/tex]

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[tex]r^{2}[/tex]

π = 3.14

Radius, r = 10 cm

A = 1/4 *3.14 * [tex]10^{2}[/tex]

A = 1/4 *3.14 * 100

A = 1/4 *314 [tex]cm^{2}[/tex]

A = 78.75 [tex]cm^{2}[/tex]

Now, multiply by 3

3 * 78.75

= 236.25  [tex]cm^{2}[/tex]
