Question

The formula for the circumference of a circle is C=2 nr. What is the radius of a circle with a

circumference of 22 cm?

Answer 1

The formula for the circumference of a circle is C = 2πr, where r is the radius and C is the circumference. The equation solved for r is r =c/2π .

Step-by-step explanation: hope this helped!

Answer 2

The radius of the circle with circumference 22cm is 3.5 cm

Explanation:

The circumference of circumference of a circle is the distance of its closed boundary.

The circumference of a circle with radius r is given by the formula:

`C = 2\pi r`

Given

C = 22cm

Putting the values in the formula

`22 = 2 * (22)/(7) * r\\22 = (44)/(7) * r\\r = (7)/(44) * 22\\r = (7)/(2)\\r = 3.5cm`

Hence,

The radius of the circle with circumference 22cm is 3.5 cm
