A circular garden will be enclosed with a barbed wire fence that is 25 feet. What is the area of the garden? Use 3.14 for pi and round to the nearest tenth.

Question

I found the radius. It was a long decimal, and I didn’t know whether I should round it then or wait until I find the total area to round. 

Answer 1

C = πd

25 / π = d

25 / π = 2r

12.5 / π = r

A = πr²

A = π(12.5/π)²

A = π(156.25/π²)

A = 156.25 / π
