Answer 8

You know the formula for the circumference.
You know the diameter.
Divide the diameter by 2 to get the radius.
Find the circumference of the circle, and divide by 2 to find the circumference of the semicircle.

Answer 9

LOL

Answer 10

\(\sf CIRCUMFERENCE = 2 \times \pi \times radius \)

Where \(\sf radius = \dfrac{1}{2} diameter \)

We, can then rewrite the equation of circumference into:

\(\sf CIRCUMFERENCE = 2 \times \dfrac{1}{2} diameter \times \pi\)

Do you see how you can simplify it?
