The top of a pie container is a circle. The radius of the pie is 8 inches and the radius of the container is 9 inches. What is the difference between the circumference of the container and the circumference of the pie in inches to the nearest tenth?

The difference of the circumference of the pie container and pie is 6.3 inches.

Step-by-step explanation:

Given,

The radius of the pie container (R) = 9 in

The radius of the pie (r) = 8 in

To find the difference of the circumference of the pie container and pie.

Formula

The circumference of a circle = 2πr

Now,

The circumference of the pie container = 2*π*9 = 18π in

The circumference of the pie = 2*π*8 = 16π in

Hence,

The difference = 18π-16π = 2π = 6.28 = 6.3 inches (approx)
