Question

The volume of a cone is 6280 cm² and it's base radius is 30 cm. Find its perpendicular height ( π = 3.14)

Answer 1

Answer:

h=6.667

Step-by-step explanation:

volume of cone=1/3×π×r^2×h

where r-radius

h-perpendicular height

so now solution:-

let perpendicular height be x

1/3×3.14×900×x = 6280

3.14×300×x = 6280

942×x=6280

x=6280/942

x=6.667

so h= 6.667
