Question

Solve

a cylinder of radius r cm and height h cm has a curved surface area A cm
`{}^(2)`, where
`A = 2\pi rh.`
a) obtain a formula for h
b) find the value of h when A = 93 ,R = 2.5 and
`\pi`= 3.1​​

Answer 1

(a) h = A/2πr

(b) 360.375

Explanation:

(a) divide both sides by 2πr

h = A/2πr

(b) h= 93 / 2*3.1*2.5

= 360.375
