Question

Chris used 45 ft of fencing to enclose a circular garden. What is the approximate radius of the garden?

Answer 1

7.2 ft

Explanation:

Here we're told that the circumference of the garden is 45 ft.

We want to determine the radius of the garden.

The formula for circumference is C = 2πr, and this C = 45 ft:

45 ft = 2πr. Solving for r: r = (45 ft) / (2π) = approx. 7.2 ft
