Answer 1

112.98

Explanation:

37.68/2π = 5.9969

5.9969²π = 112.98

Answer 2

The area is 112.9 square units to the nearest tenth.

EXPLANATION

The circumference is given by:

`C=2\pi \: r`

This implies that,

`37.68 = 2 \: \pi \: r`

`(37.68)/(2\pi) = r`

`r = 5.997`

The area of a circle is

`\pi \: {r}^(2)`

We substitute the radius to get;

`3.14 * 5.997 ^(2) = 112.93 \: sq. \: units`

To the nearest tenth, the area of the circle is 112.9 square units.
