Answer 2

Answer

The vertical height of the given cone is 6 cm .

Solution

As given that -

Base radius of cone is 7cm

Volume of cone is 308cm³ also volume of cone is 1/3πr²h .So putting both volumes equivalent ,

Calculation

→ 308 = 1/3 π r²h

→ here r = 7cm and π =$\frac{22}{7}$

→ 308 × 7×3/22×7×7 = height

→ 44 × 3/ 22. = height

→ 6. = height

So , vertical height of cone is 6 cm
