Question

the diameter of cylinder is 30 cm and its height is 35 cm find the surface area of cylinder​

Answer 1

$\huge{\mathfrak{\blue{\underline{Answer}}}}$

Diameter of cylinder = 30cm

✝ Radius = diameter/2 = 30cm/2 = 15cm

✝ Hieght = 35cm

✝ Surface area of the cylinder :

$= \pi \: r(h + r) \\ = \frac{22}{7} \times 15cm(35 cm + 15cm) \\ = \frac{22}{7} \times 15cm(50cm) \\ = 2357.14cm {}^{2}$
