Question

I need help with this one

Answer 1

112.98 square units

Explanation:

Let's work backwards:

Circumference = 2πr

(37.68)/2π = r

Area = π
`r^(2)`

Area = π *
`((37.68)/2pi)^(2)`

Area = 112.983 square units

Answer 2

Explanation:

Circumference = 37.68 units

2πr = 37.68

2*3.14*r = 37.68

`r=(37.68)/(2*3.14)\\\\`

r = 6 units

Area =πr²

= 3.14*6.6

= 113.04 square units
