Question

A circular fountain has a radius of 6.1 feet. Find its diameter and circumference to the nearest hundredth. Use 3.14 for π.

Answer 1

d= 12.2 C= 38.3

Explanation:

The radius of a circle is half of the diameter so multiply 6.1 by 2

6.1 x 2 = 12.2 ft

To find the circumference:

C = 2πr

C = 2(3.14)(6.1)

C= 2(19.154)

C= 38.3
