Answer

$$987~cm^3, \ 568~cm^ .$$

Work Step by Step

The volume of the cylinder is given by $$ volume= area \ of \ base \times height=r^2\pi \times height= (8.92/2)^2 \times \pi\times 15.8=987.36\ cm^3\approx 987~cm^3 .$$ The surface area of the cylinder is given by $$ Surface \ area =2 r^2\pi +2r\pi \times height=2 (8.92/2)^2 \times \pi+8.92\pi\times 15.8=567.746\ cm^2\approx 568~cm^ .$$
