Question

The diameter of a circular swimming pool is 10 feet. Find its circumference. Round to the nearest tenth.

Use 3.14 for it.
d = 10 ft.

Answer 1

Answer:30

Explanation:

circumference of a circle= 3.14xd

3.14x10=31.4ft

30ft(to the nearest tenth)

Answer 2

31.4 ft squared

explanation

the circumference of a circle is c = 2r * pi = d * pi

plug in 10 for d (diameter) and 3.14 for pi

c = 10 * 3.14

c = 31.4 ft squared
