Question

Find the surface area of the cylinder. Use 3.14 for \pi " alt=" \pi " align="absmiddle" class="latex-formula">

Answer 1

Suface area= 2πrh+2πr²
                    = 2×3.14×2×15+2×3.14×2²
                   = 6.28×2×15+6.28×4
                   =188.4+25.12
                 =213.52
so Surface area=213.52cm
