Question

The volume of frustum of a cone is calculated by using the formula ______
  1. V = πh3(R2+Rr+r2)
  2. V = πh3(R2Rrr2)
  3. V = πh3(R2Rr+r2)
  4. V = πh3(R2+Rrr2)

A
V = πh3(R2+Rr+r2)
B
V = πh3(R2Rr+r2)
C
V = πh3(R2Rrr2)
D
V = πh3(R2+Rrr2)
Solution
Verified by Toppr

The volume of frustum of a cone is calculated by using
the formula V = πh3(R2+Rr+r2)
where R is radius of base circle; r
is radius of top circle; h is height or distance between the
centres of the base and the top circles.
