Question

Find the surface area of a cylinder with a base radius of 3 m and a height of 6 m. Write your answer in terms of pi, and be sure to include the correct unit. ​

Answer 1

• Radius=r=3m
• Height=h=6m

`\\ \sf\longmapsto SA=2\pi rh`

`\\ \sf\longmapsto SA=2(3.14)(3)(6)`

`\\ \sf\longmapsto SA=6.28(18)`

`\\ \sf\longmapsto SA=113.04m^2`

Answer 2

• 36π m²

Explanation:

Finding the lateral surface area as it doesn't ask for full surface area:

• A = 2πrh

Substitute r = 3 and h = 6:

• A = 2π*3*6 = 36π
