A French Fry Stand At The Fair Serves Their Fries In Paper Cones. The Cones Have A Radius Of 2 Inches And A Height Of 6 Inches. It Is A Challenge To F

A french fry stand at the fair serves their fries in paper cones. The cones have a radius of 2 inches and a height of 6 inches. It is a challenge to fill the narrow cones with their long fries. They want to use new cones that have the same volume as their existing cones but a larger radius of 4 inches.

What will the height of the new cones be?

Answer:

1.5 inches

Step-by-step explanation:

First, we need to find out the volume of the cone that was in use.

Volume of a cone can be found using the formula 1/3 πr²h.

Find volume:

Volume = 1/3 πr²h

Volume =  1/3 π(2)²(6) = 8π in³

Now that we know the volume, we can find the new height by applying the formula of the volume one more time and changing the radius to 4 in.

Find the new height:

Volume = 1/3 πr²h

8π = 1/3 π(4)²h

8π = 16π/3 h

h = 8π ÷ 16π/3

h = 3/2 in or 1.5 in

Answer: The new height is 1.5 inches.
