Question

A circular swimming pool has a diameter of 12 feet. What is the circumference the pool? Use 3.14 to approximate for π . Enter your answer, as a decimal rounded to the nearest tenth, in the box.

Answer 1

d= diameter= 12 ft

STEP 1
find radius

r= radius
= 1/2d
= 1/2(12)
= 6 ft


STEP 2
find circumference

Circle Circumference Formula
C= 2πr
C= 2(3.14)(6)
C= (12)(3.14)
C= 37.68 ft^2


ANSWER: The pool's circumference is 37.7 ft^2 (rounded to nearest tenth).

Hope this helps! :)
