Question

Express the required calculation in terms of pi

and then round to the nearest tenth.
How much fencing is required to enclose a circular garden whose radius is 30

​meters?

Answer 1

The formula for the circumference of a circle is C = 2πr, where r is the radius.

Thus, the fencing required to enclose a circular garden with a radius of 30 meters would be:

C = 2π(30)
C = 60π

Rounding to the nearest tenth, the answer is:

C ≈ 188.5 meters
