A bucket has ...

Question

A bucket has top and bottom diameter of 40 cm and 20 cm respectively. Find the volume of the bucket if its depth is 12 cm. Also, find the cost of tin sheet used for making the bucket at the rate of Rs. 1.20 per dm². (Use π = 3.14)

Open in App

Solution

The radii of the top and bottom circles are r₁ = 20 cm and r₂ = 10 cm respectively. The height of the bucket is h = 12 cm. Therefore, the volume of the bucket is

The slant height of the bucket is

The total surface area of the bucket is

The total cost of tin sheet used for making the bucket is
