Question

if the radii of the circular ends of a conical bucket which is 16 cm and height 20 cm and 8 cm find the capacity and total surface area of the bucket

Answer 1

vol = 197120/21
and tsa =find out by adding the area of the lower base of the bucket with its csa

Answer 2

Volume of cone(bucket)- 1/3*pie*r^2h
- 1/3*22/7*16*16*20.
Total surface area: pie r(l+r)
-22/7*16*(20+16)
