Answer 1

100 pi feet it's D

Explanation:

trust me i took the test

Answer 2

The maximum area that the goat can graze is 400
`\pi` square feet.

Explanation:

The maximum area that the goat can graze is the area of the circle that can be formed due to its circular movement. The length of the rope represents the radius of the circle, so that;

Area of a circle =
`\pi`
`r^(2)`

Where r is the radius and equals 20 feet in the given question.

Thus,

Area =
`\pi`
`(20)^(2)`

= 400
`\pi`

Area = 400
`\pi` square feet

The maximum area that the goat can graze is 400
`\pi` square feet.
