Question

C=72.6 what is the radius and diameter

Answer 1

Answer:

The circumference of a circle=2*pi*r

where,

• pi=3.14
• r is the radius of the circle

Given that the circumference is:

C=72.6

72.6=2×3.14*r

72.6=6.28r

6.28r=72.6

r=72.6/6.28

r=11.56

Diameter of a circle=2×radius

d=2×11.56

Diameter=23.12
