Question

Work out the surface area of this cylinder 8.2 cm 17.5 cm

Answer 1

Answer: 1324.12 sq. cm.

Step-by-step explanation:

A=2πrh+2πr2

A = 2π x 8.2 x 17.5 + 2π x 8.2^2

A = 2π x 143.50 + 2π x 67.24

A= 1324.12

Answer 2

Answer:

SA = 1324.1 cm²

Step-by-step explanation:

Surface Area of Cylinder = $2\pi rh+2\pi r^2$

Where r = 8.2 cm, h = 17.5 cm

=> SA = $2(3.14)(8.2)(17.5)+2(3.14)(8.2)^2$

=> SA = $901.6+2(3.14)(67.24)$

=> SA = 901.6 + 422.5

=> SA = 1324.1 cm²
