I need help 20 points

Answer 1

Answer: 84.825

Explanation:

area of circle = pi r squared.

radius is 6. plug in numbers for area.

the whole circle is 113.1 x 3/4 is 84.825

Answer 2

`A = 9\pi`

Explanation:

This is basically just 3/4 of a circle, so the area will be:

`A = (3)/(4) \pi r^(2)`

Plug in 6 for the radius:

`A = (3)/(4) \pi (6)^(2)`

Simplify:

`A = (3)/(4) \pi (36)`

Simplify further:

`A = 9\pi`
