Answer 1

Answer:

13.7$cm^{2}$

Step-by-step explanation:

to work this out you need to find the area of the square.

The formula for working out the area of a square is to multiply the length and the width together.

So you would multiply 8 by 8 to give the area of this square.

$8*8=64cm^{2}$

You would then need to work out the area of the circle using the formula:

$\pi r^{2}$

$\pi *4^{2}$=50.27$cm^{2}$

Then to work out the area shaded you will subtract the area of the circle from the area of the square to give you the area of the shaded region.

$64-50.27$=13.73

rounded to 13.7

This is for question 22
