Question

What is the area of the composite figure?

(6pi+4) cm
O(6pi+16) cm
0 (12pi +4) cm
0 (12pi+16) cm
2 cm

Answer 1

Answer:
`6\pi +4`

Explanation:

The normal formula for area of a circle is
`\pi r^2` so remember it. Itll be important for the rest of your life. Now this isnt a normal circle, this is a semi circle. So, you should divide by 2.

Three Semi-Circles:

We are given the radius which is 2 cm.
`(\pi2^2 )/(2) =2\pi`

Now we gotta multiply that answer by 3 because there are three semi circles.

`(2\pi )(3)=6\pi`

Area of a Square:

This is simple, do
`s^2` to get 4
