Question

The height of a circular cylinder is 15 cm and radius of its base is 28 cm find its volume and total surface

Answer 1

Hey....☺

Volume of cylinder = πr^2h
= 22/7 × 28 × 28 ×15
22× 4 × 28×15
= 18480 cm^3


T.S A of cylinder = πr(r+h)
= 22/7 × 28 ( 28+ 15)
= 22× 4 × 43
=1892 cm^2

:) ,Hope this helps

Answer 2

Hey!!!
________________________________
●For cylinder
Height=15cm
Radius=28cm
so,volume=
$\pi {r}^{2} h \\ = \frac{22}{7} \times 28 \times 28 \times 15 \\ = 39960 {cm}^{3}$
and Total surface area(TSA)=
$2\pi \: r \times (h + r) \\ = 2 \times \frac{22}{7} \times 28 \: (15 + 28) \\ = 176 \times 43 \\ = 7568 {cm}^{2}$
