Answer 1

Given: Radius of base (r) and height (h) of the conical tank are 7 m and 24 m
⇒ Slant height (l) = r 2 + h 2 
                            =  (7 m) 2 + (24 m) 2 
                            = 49m 2 + 576m 2 
                            = 625m 2 
                            = 25m
Thus,
Curved surface area = πrl =  22 7 × 7 × 25 m 2 = 550m2
 for,
10 cones = 550 x 10 = 5500m2

now,
 for 2mts = 40 rs
 so,
 for 5500mts = 5500 x 40/2
                    = 5500 x 20
                rs = 1,10,000-/-
 
he was indeed a generous man,
hope this helped u,
