Value 1:

r = 5ft, h = 10ft. Substitute:

`SA=2\pi(5)(10)+2\pi(5^2)=100\pi+50\pi=150\pi\ ft^2`

Value 2:

r = 2in, h = 4in. Substitute:

`V=(1)/(3)\pi(2^2)(4)=(1)/(3)\pi(4)(4)=(16\pi)/(3)\\\\\pi\approzx3.14\to V\approx((16)(3.14))/(3)\approx16.75\ in^3`

Value 3:

r = 6m. Substitute:

`V=(4)/(3)\pi(6^3)=(4)/(3)\pi(216)=4\pi(72)=288\pi\ m^3\\\\\pi\approx3.14\to V\approx288(3.14)=904.32\ m^3`
