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.

stellarik [79]

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.
