Answer 1

Area: 50.24 units^2

Explanation:

Area of Circle: pi x r^2

Radius: 4

Pi: 3.14

Area: 3.14 x 4^2

Area: 3.14 x 16

Area: 50.24

I think it wants you to find the area of 3/4ths of that circle.

So what you would do is divide the actual area of a full circle by 4.

50.24/4 = 12.56

Then. subtract it from the area of a circle to get the area of your shape.

50.24 - 12.56 = 37.68

Therefore, your new answer would be 37.68.

Answer 2

12π units²

Explanation:

The shape is three quarters of a circle

The area (A) is calculated as

A = area of circle × fraction of circle

A= πr² ×
`(3)/(4)`

= π × 4² ×
`(3)/(4)` = 16π ×
`(3)/(4)` = 12π units²
