Question

Find the surface area

Answer 1

Surface Area formula of a cylinder:
S.A = 2 × Area of base + Perimeter of base × Height of prism
= 2
`\pi`r² + 2
`\pi`rh
= 2
`\pi`(5)² + 2
`\pi`(5)(18)
= 50
`\pi` + 180
`\pi`
= 230
`\pi` in² ( in terms of
`\pi` )
= 722.566 in²
= 722.7 in² ( to the nearest tenth )
