Question

If the circumference of the circle is 132m. Then calculate the radius and diameter

Answer 1

2•(pi)•(radius)=132
radius = 21.02 m (or 22 m if you set pi = 3)
2•(radius) = diameter
diameter = 42.04 m

Answer 2

Answer:

Radius: 21.02 m

Diameter: 42.04 m

Step-by-step explanation:

Circumference of circle = 2 · π · r

132m = 2 · π · r

66 m = π · r

r ≈ 21.02 m

Diameter = 2 · r

21.02 · 2 = 42.04 m

So, Radius = 21.02 m

     Diameter = 42.04
