Question

The total surface area of a cylinder is 528cm2 and the diameter of its base is 12 cm find the height

Answer 1

let the height of the cylinder be h cm

$formulae$

$\Rightarrow$ $TSA$ = $2πrh(h + r)$

$\Rightarrow$ $CSA$ = $2πrh$

$\Rightarrow$ $Volume$ = $2πhr$²

______________________________________

Given:-

$\Rightarrow$ Total surface area = 528cm²

Diameter of the base = 12cm

Radius = $\dfrac{6}{2}$ = 6 cm.

ATQ

TSA = 528cm²

$\Rightarrow$ $2πrh(h + r)$ = 528cm²

= 2 × 22/7 × 6(h+6) = 528

= h + 6 = 528/22 × 7 /2 × 1/6

= h = 14cn.
