A french fry stand at the fair serves their tries 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?

1.5 inch

Step-by-step explanation:

The existing cones have a radius of 2 inches and a height of 6 inches.

Since the new cones is to have the same volume as the existing cones, we determine first the volume of the existing cone.

Volume of a Cone =

For the existing cone, Radius, r =2 inches, Height, h= 6 inches

Volume of the existing cone = cubic inch

Recall, Volume of the new cones = Volume of the Existing Cone

Radius, r of the new cone = 4 inches

Volume of the new cones=  

Dividing both sides by

To solve for the height, h, multiply both sides by

The height of the new cone will be 1.5 inch.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )

you can't solve x because it is 2 linear equation and you only have one equation
