Question

a circular mat has a circumference of 220 centimeters find the radius rounderd to the nearest whole number

Answer 1

Answer:

The answer is 32cm

Step-by-step explanation:

Circumference of a circle = 2πr

where

r is the radius

To find the radius of the mat substitute the value of the circumference into the above formula and solve for the radius

Circumference = 200cm

200 = 2πr

Divide both sides by 2π

$r = \frac{200}{2\pi}$

r = 31.83098

We have the final answer as

radius = 32 cm to the nearest whole number

Hope this helps
