Diameter, Area, Circlular - Math word problem - PLEASE HELP

Question

Farmer Brown is prepping his circular garden for the new spring / summer season of vegetables. The garden has to be larger than 25 square feet. If the diameter of the garden is 10 cm, what is the area? Does the farmer have enough space to plant his vegetables? Explain.

Answer 1

The area (A) of a circle with a radius, r, can be calculated using the following formula:

A = ¶ • r²

In this problem, the radius of the garden is 5 cm. 5 cm is very small for a garden - did you mean 5 feet??

I'll assume you meant 10 feet for the diameter. In this case, the radius is 5 feet.

The area of the garden with a radius of 5 feet is:

(Using 3.14 for pi)

A = 3.14 • 5²

A = 3.14 • 25

A = 78.5 square feet

Yes he will have enough space because 78.5 is larger than the necessary 25 square feet.
