Answer:

1155.52 cm²

Explanation:

SA = LSA (Pb x h) + 2B

- r = 8 cm, h = 15, π (pi) = 3.14

Lateral Surface Area (LSA) = Pb (Perimeter of base) x h (height)

8 x 2 = 16 x 15 = 240 x 3.14 = 753.6

Area of the Base x 2 = πr² x 2

8² x 3.14 = 64 x 3.14 = 200.96 x 2 = 401.92

753.6 + 401.92 = 1155.52

Answer:

Surface Area of the Cylinder is 1156.11

Explanation:

To find the Surface Area of a Cylinder, the equation given is A = 2πrh+2πr2

Given the radius and height of the cylinder, we plug those numbers into the equation to get;

A = 2π(8)(15)+2π(8)2

= 1156.11
