Question

A rotating sprinkler waters a circular region of a lawn with a diameter of 50 feet. What is the area of the lawn being watered? Use 3.14 for Pi. Enter your exact value - DO NOT ROUND!!

Answer 1

1962.5

Explanation:

Multiply 25 x 25 then multiply that by 3.14.

Answer 2

A =1962.5 ft^2

Explanation:

We want to find the area of the circle

A = pi * r^2

We know the diameter

d = 2r

50 = 2r

Divide by 2

50/2 = 2r/2

25 =r

A = pi * (25)^2

A = pi*625

Let pi = 3.14

A = (3.14) * 625

A =1962.5 ft^2
