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 19

​meters?

Answers

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

So, the amount of fencing required would be:

C = 2π(19)

C = 38π

Rounding to the nearest tenth:

C ≈ 119.4 meters
