Answer 2

$\huge\mathfrak{Answer}$

Given that,

Slant height of conical tomb ( L ) = 25 m

Diameter of conical tomb ( D ) = 14 m

Radius of conical tomb ( r ) = 14/2 = 7 m

Curved surface area of tomg = $\pie$rl

$\frac{22}{7} \times 7 \times 25 = 550 {m}^{2}$

Cost of the white washing 100 m² = 210 rs

Cost of white washing 1 m² = 210/100

Cost of white washing 550 m²

$= \frac{210}{100} \times 550 = 1155rs$

So, the cost of white washing its curved surface at the rate of 210 rs per 100m² is 1155 rs
