Answer

$S.A.=979.7yd^2$ $V=2260.8yd^3$

Work Step by Step

The surface area of a cylinder can be found with the formula: 2$\pi$$r^2+2$$\pi$$rh$ Substitute the given values into the formula and use $3.14$ for $\pi$: $S.A.=2(3.14)(6^2)+2(3.14)(6)(20)=979.68$ Round the answer to the nearest tenth: $979.7$ The volume of a cylinder can be found with the formula: $\pi$$r^2h$ Substitute the given values into the formula and use $3.14$ for $\pi$: $V=3.14(6^2)(20)=2260.8$
