Question

What is the area ? 3.14 = pi

Answer 1

236.25
`cm^(2)`

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
`r^(2)`

π = 3.14

Radius, r = 10 cm

A = 1/4 *3.14 *
`10^(2)`

A = 1/4 *3.14 * 100

A = 1/4 *314
`cm^(2)`

A = 78.75
`cm^(2)`

Now, multiply by 3

3 * 78.75

= 236.25
`cm^(2)`
