Answer 1

this is the ans of your question

Answer 2

Given :-

• Diameter = 14 m

Radius = 7 m

• Height = 25 m

To find :-

• Curved surface area of the tomb &
• Cost of white washing

According to the question,

Curved surface area of the tomb = $\sf{ \pi rl}$

$\implies \sf{ \frac{22}{7} \times 7 \times 25}$

$\implies \sf \red{ 550 \: {m}^{2} }$

.°. Cost of white washing at the rate of Rs 12

$\implies \sf{550 \times 12}$

$\implies \sf\red{Rs\:6600}$
