Answer 5

Ok so for the first one you need the circumference, since you have the diameter you can use the formula,

\[C = \pi d\] where d is the diameter.

For the area, use \[A = \pi r^2\]

and for semi circle use \[A = \frac{ 1 }{ 2 } \pi r^2\]

where the r in the formula = radius.

Answer 6

Diameter = 2*radius
