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?

The formula for the volume of a right circular cone is V = \pi  r^{2} h. In solving for the volume of the first french fries cones V = \pi ( 2^{2} )(6) = 75.398 in^{3}. In solving for the height of the second french fries cones with a new radius of 4, the formula is rearranged to h =\frac{V}{ \pi  r^{2} } = \frac{75.398}{ \pi  (4^{2}) } = 1.5 in or inches. The height of the new cones will be 1.5 inches.

ASHA 777 [7]

Answer:

4

Step-by-step explanation:

8% is also 8/100. This would be true for all percents 0 to 100%. If it were 42% it can be written as 42/100.

So, 8% is 8/100. If you want to find 8/100 of 50 multiply them.

8/100 * 50/1 = (8*50) /100

400/100 = 4
