A_{L} = 8π √(9^{2} + 8^{2})

A_{L} = 8π√145

Now multiply by 16 to get the amount of paper needed.

A_{L} = 8π √(9^{2} + 8^{2})

A_{L} = 8π√145

Now multiply by 16 to get the amount of paper needed.

pi * r * (r + sqrt( h^2 + r^2) )

pi * 8 * (8 + sqrt( 81 + 64) )

pi * 8 * (8 + sqrt(145))

which is approximately 503.7

....

multiplies by 21
