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.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
