Question

A right cylinder has a diameter of 10 in and height of 15 in. Find the surface area of the cylinder.

Answer 1

`\huge{ \underline{ \mathcal{Given : }}}`

• Diameter = 10 in

• radius (r) = 5 in

• height (h) =15 in

`\huge{ \mathcal{ \underline{ solution} }}࿐`

`\boxed{Area =2 \pi r(h + r)}`

• 
  `2 * 3.14 * \ 5 * (5 + 15)`

• 
  `31.4 * 20`

• 
  `628 \: \: in {}^(2)`

Surface Area = 628 in²

Answer 2

628.32 in.²

Explanation:

Height: 15 in.

Diameter: 10 in.

Radius: 5 in.

A = 2πrh + 2πr²

2 · π · 5 · 15 + 2 · π · 5²

≈ 628.32
