Question

A goat is placed in a circular pen with a radius of 15 feet. The formula for the area of a circle is A=πr2, where r is the radius. If π=3.14, on how many square feet of grass can the goat graze in the pen?

Answer 1

765
`ft^(2)`

Explanation:

A =
`\pi r^(2)`

A = (3.24)
`15^(2)`
`15^(2)` means 15 x 15

A = (3.14(15)(15)

A = 765
