Question

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

Answer 1

Answer:

628.32 in.²

Step-by-step explanation:

Height: 15 in.

Diameter: 10 in.

Radius: 5 in.

A = 2πrh + 2πr²

2 · π · 5 · 15 + 2 · π · 5²

≈ 628.32

Answer 2

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

• Diameter = 10 in

• radius (r) = 5 in

• height (h) =15 in

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

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

• $2 \times 3.14 \times \ 5 \times (5 + 15)$

• $31.4 \times 20$

• $628 \: \: in {}^{2}$

Surface Area = 628 in²
