Radius =10/2= 5 m
Slant height,
l= 4.2 m
Area of curved surface =π× r× l
                                      =22/7×5×4.2
on solving we get,
Area= 66 m²
Length of the canvas cloth =66/3 = =22 m

Now, cost = 22×2.50 =Rs 55

radius of the canvas cloth =10/2 =5M
height of canvas =4.2m

area = pie ×r ×h =22/7×5×4.2 on solving we get 66m^2 length of canvas cloth =66/3=22 cost of canvas cloth=22×2.5=55
