Unformatted text preview: 2 S.A. = 49(6) S.A. = 294 in 2 Surface Area of a Cylinder A cylinder consists of two circle bases and one rectangular side. The length of the rectangle is equal to the circumference of the circle. Find the area of the circles and add it to the area of the rectangle. Example 5 m 16 m Area of the circles A = r 2 A = 3.14(5 2 ) A = 3.14 (25) A = 78.5 m 2 2 circles: 78.5 x 2 = 157 m 2 Rectangle The width of the rectangle is the height of the cylinder (16 m). The length of the rectangle is the circumference of the circle. C = 2 r C = 2(3.14)(5) C = 31.4 m A = lw A = 31.4(16) A = 502.4 m 2 Put the areas together: S.A. = 157 m 2 + 502.4 m 2 S.A. = 659.4 m 2 Homework Time...
