a circular mat has a circumference of 220 centimeters find the radius rounderd to the nearest whole number
1 answer:
Answer:
<h3>The answer is 32cm</h3>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 = 31.83098
We have the final answer as
<h3>radius = 32 cm to the nearest whole number</h3>Hope this helps
