Answer:
13.7[tex]cm^{2}[/tex]
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.
[tex]8*8=64cm^{2}[/tex]
You would then need to work out the area of the circle using the formula:
[tex]\pi r^{2}[/tex]
[tex]\pi *4^{2}[/tex]=50.27[tex]cm^{2}[/tex]
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.
[tex]64-50.27[/tex]=13.73
rounded to 13.7
This is for question 22
