Question

A cone with a radius of 6 cm has a volume of 1200 cm3. What is the height of the cone? (The volume of a cone is given by the formula V = 7er A) 8 cm B) 10 cm 12 cm D) 15 cm​

Answer 1

• 31.8 cm

Explanation:

Volume of a cone:

• V = 1/3πr²h

We have:

• V = 1200 cm³
• r = 6 cm
• h = ?

Substitute values and solve for h:

• 1200 = 1/3*3.14*6²h
• 1200 = 37.68h
• h = 1200/37.68
• h = 31.8 cm (rounded)
