Question

if the radius of a cylinder is 6cm, height of cylinder is 49cm then find its value ​

Answer 1

Answer:

12cm

Step-by-step explanation:

and follow please

Answer 2

Volume of cylinder =πr²h

$\pink{ \large{ \longrightarrow \: \frac{22}{7} \times 6 \times 6 \times 49}}$$\pink{ \large{ \longrightarrow \: 22 \times 6 \times 6 \times 7}}$

$\pink{ \large{ \longrightarrow \: 22 \times 6 \times 6 \times 7}}$

$\huge{ \pink{ \Longrightarrow \: 5544 \: {cm}^{3} }}$

__________________________

TSA of Cylinder =2πr(h+r)

$\pink{ \large{ \longrightarrow \: 2 \times \frac{22}{7} \times 6(49 + 6) }}$

$\pink{ \large{ \longrightarrow \: 2 \times \frac{22}{7} \times 6 \times 55 }}$

$\pink{ \large{ \longrightarrow \: \frac{14520}{7} }}$

$\pink{ \huge{ \Longrightarrow \: 2074.29 \: (approx) }}$
