Question

The diameter of a circle is 34 feet. what is the circles circumference ?

Answer 1

π=3.14
d=diameter
C= πd
C=3.14*34
C=106.76 sqaure feet <==answer

Answer 2

106.81

Explanation:

first convert diameter to radius

• radius = diameter / 2
• radius = 34/2 = 17

now find circumference

• circumference = 2πr
• circumference = 2π(17) = 106.81

r = radius
