How to find the total surface area of a cylinder 10m 25m SA = 2 r² + 2 rh or 2 r(r + h) = 2 = 700 Use 3.14 for = 700 3.14 = 2198 m² (10 + 25) 35 = 2 35
How to find the lateral surface area of a cylinder 12m 28m SA = 2 rh = 2 = 672 Use 3.14 for = 672 3.14 = 2110.08 m² 28 = 2 28 Finding the lateral surface area of a cylinder is like finding the AREA of a LABEL on a can
