Answer:

42.0

Explanation:

For this question we are given the circumference of a circle which is 132 and we are asked to find diameter of the circle. We need to utilise one important formula which the circumference of a circle formula

Circumference of a circle = π × d

We need to make 132 equal to the circumference of a circle formula so then we can work out the diameter by forming an equation to solve for the diameter so,

⇒ Form the equation

→ π × d = 132

⇒ Divide both sides by π to isolate d

→ d = 42.0169049763

The diameter of the circle with a perimeter of 132 is 42.0 to 1 decimal place

Answer:

42

Explanation:

The perimeter of circle is same as it’s circumference.

Circumference = π * D

132 = 22/7 * D

22D = 7 * 132

22D = 924

D = 924/22

D = 42
