Question

7. The circumference of the base of a cylinder is 88 cm and its height is 60 cm. Find the
volume of the cylinder and its curved surface area.​

Answer 1

Answer:

First we have to find the radius

Circumference = 88

we know that formula of circumference is 2×22/7×r=88

Step-by-step explanation:

2×22/7×r=88

=) r=88×7/22×2

=)r=7

Volume =22/7×7×7×60

=)9240

Curved Surface Area =2×22/7×7×60

=)2640

Answer 2

7. The circumference of the base of a cylinder is 88 cm and its height is 60 cm. Find the volume of the cylinder and its curved surface area.

Solution-

$\underline \bold{circumference \: of \: cylinder = > 2\pi \: r} \\ \\ 88cm = > 2 \times \frac{22}{7} \times r \\ \\ \frac{88cm \times 7}{44} = > r \\ \\ \color{red} \boxed {r = > 14cm}$

$\boxed{\underline \bold \red {csa \: of \: cylinder= > 2\pi \: rh}}$

$= > 2 \times \frac{22}{7} \times 14 \times 60 \\ \\ = > 88cm \times 60cm \\ \\ = > 5280 {cm}^{2}$

$\boxed{ \underline \bold \blue{csa \: of \: cylinder = > 5820 {cm}^{2} }}$

$\boxed { \underline \bold \pink{volume \: of \: cylinder = > \pi \: {r}^{2}h }}$

$= > \frac{22}{7} \times 14 \times 14 \times 60 \\ \\ = > 36960 {cm}^{3}$
