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

Answer 1

Answer:

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 .

Answer 2

Answer:

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

Step-by-step 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

$22 = 2 * \frac{22}{7} * r\\22 = \frac{44}{7} * r\\r = \frac{7}{44} * 22\\r = \frac{7}{2}\\r = 3.5cm$

Hence,

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