Question

The curved surface area of a cylinder of height 28cm is 352sq.cm. Find the diameter of the base of the cylinder​

Answer 1

Answer:

d = 4cm

Step-by-step explanation:

curved surface area (CSA) of cylinder = $2\pi rh$

h = 28cm and CSA = 352$cm^{2}$

$2\pi rh$ = 352

2 * $\frac{22}{7}$ * r * 28 = 352

$r = \frac{352*7}{2*22*28}$

after calculating, you will get r = 2cm

so diameter = 4cm
