Use 3.14 for , and do not round your answer. Be sure to include the correct unit in your answer.

Answer 1

81.64 meters

Explanation:

The formula for circumference is C=2πr. In your case, you will use 3.14 instead of π. The diameter is 26m, which should be divided by 2 to get the radius.

26/2=13

Then, plug everything in the formula:

C=2×3.14×13

C=81.64m

Answer 2

81.64 ft

Explanation:

To find the circunference, You need to know the formula first. that is:

C= πd or 2rπ

so;

26 x 3.14 is

81.64.
