Best ResponseYou've already chosen the best response.1well the surface area formula is \[SA = 2\pi r^2 + 2 \pi r h\] with r = 7 \[461.8 = 2\times \pi \times 7^2 + 2 \times \pi \times 7 \times h\] subtracting the area of the circles from both sides \[461.8  98\pi = 14\pi h\] divide both sides by 14 pi \[h = \frac{461.8  98\pi}{14\pi}\] now you can calculate the value of h
