Question

a plate has a raduis of 3 inches what is the best approximation for the circumference of the plate ? use 3.14 to approimate pi.​

Answer 1

Best approximation for the circumference of the plate = 18.84 inches

Explanation:

Given in the question,

radius of a plate = 3 inches

π = 3.14

To find,

circumference of the plate.

As we know that formula to calculate circumference of a circle given radius

2 π r

2 (π) (3)

2 (3.14) (3)

18.84 inches

So the circumference or perimeter of area = 18.84 inches
