The circumference of a circular garden is 628 feet. Find the area of the garden

Question

First find the radius of the garden

Answer 1

Circumference = piD = 628

Diameter = 628/pi = about 628/3.14 = about 199.9

Radius = D/2 = 199.9/2

= about 99.95 feet from garden's center to its edge

Area= pi(R^2) = pi(628/pi)^2

= 628^2/pi

=394,384/pi

= about 125,536.31 square feet

or

Radius = about 200 feet

Area = about pi(200^2)

= pi(40,000)

=about 3.14(40,000)

= slightly less than 125,600 ft^2
