Mayur is in charge of creating themed popcorn containers for a county fair. He plans on creating cylindrical and cone-shaped containers. Each cylindrical container, x, has a volume of 52in3, and each cone-shaped container, y, has a volume of 26in3. Both containers have a height of

5.5in. The system of equations shown can be used to find the number of cylindrical and cone-shaped containers at each snack booth in the fair.
52x + 26y = 7150
x + y = 175
What is the radius, in inches, of the cylindrical containers? Round your answer to the nearest hundredth.

A. 2.12 in
B. 1.73 in
C. 1.50 in
D. 3.01 in

1 answer

To find the radius of the cylindrical containers, we can first find the volume of a cylinder formula which is V = πr^2h, where V is the volume, r is the radius, and h is the height.

Given that the volume of each cylindrical container is 52in^3 and the height is 5.5in:
52 = πr^2*5.5
r^2 = 52 / (5.5π)
r^2 = 3.74
r = √3.74
r ≈ 1.93 inches

So, the radius of the cylindrical containers is approximately 1.93 inches, which rounds to 1.93 inches to the nearest hundredth.

Therefore, the closest answer choice is B. 1.73 in.
