Question

The diameter of a right circular cone is 10 cm and its volume is 751 cm cube . What is its height?​

Answer 1

Answer:

Volume of cone=1/3 ×22/7 ×r^2 ×h

GIVEN:

r=10/2=5cm

volume =751 cm^3

h=?

Solution:

Volume =751

1/3 ×22/7 ×5 ×5 ×h =751

h=751×3×7/22×5×5

h =15771/550

h=28.6745454545....cm

Therefore height of the cone is 28.6745cm (approx )
