Question

A circle has a circumference of 452.16452.16452, point, 16 units. What is the radius of the circle?

Answer 1

Answer:

Step-by-step explanation:

Formula used:

circumference of circle having radius r $=2\:{\pi}r\: units$

Given:

circumference of the circle = 452.16 units

$2\:{\pi}r=452.16\\\\2*\frac{22}{7}*r=452.16\\\\r=\frac{452.16*7}{2*22}\\\\r=\frac{226.08*7}{22}\\\\r=71.93\: units$

Answer 2

The radius of circle is 71.93 units.

Step-by-step explanation:

Since we have given that

Circumference of circle = 452.16 units

We need to find the radius of circle.

So, as we know that

$C=2\pi r\\\\452.16=2\times \dfrac{22}{7}\times r\\\\\dfrac{452.16\times 7}{22\times 2}=r\\\\r=71.93\ units$

Hence, the radius of circle is 71.93 units.
