Question

The diameter of a circle is 12 ft. Find the circumference round to the nearest tenth.

Answer 1

37.7

Explanation:

C = d x π

C = 12 x 3.14

C = 37.68

rounded to 37.7

Answer 2

37.7 ft

Explanation:

formula: C = πd

so circumference = π x 12 = 37.6991118

to nearest tenth = 37.7 ft

Please note this is if you take pi as π on the calculator. If it is simplified to 3.14 or 3.142, the answer will be slightly different.
