A bucket has top and bottom diameters of 40cm and 20cm respectively. Find the volume of the bucket if its depth is 12cm. Also, find the cost of tin sheet

used for making the bucket at the rate of Rs. 1.20 per dm sq. (Use pie= 3.14) How to get the cost in it?


If the answer in the picture is not correct then do this. After the volume is calculated , calculate the surface area whose formula is 3.14( (D^2 + d^2) + whole root of (D^2 - d^2)^2 + (h(D+d))^2 The above will give the surface area which is 8543.4 cm^3 and then multiply by 1.20 = 8543.4 x 1.20 = Rs 10252 Sorry for the inconvenience
