Question

The volume of the cone below is 700 cm³. Calculate the height of the cone. If your answer is a decimal, give it to 1 d.p. 8 cm​

Answer 1

10.4 cm

Explanation:

Formula used :

Volume (cone) = 1/3πr²h

=============================================================

Given :

⇒ Volume = 700 cm³

⇒ Radius = 8 cm

===========================================================

Solving :

⇒ 700 = 1/3 × π × 8² × h

⇒ 700 = 64π/3 × h

⇒ h = 700 × 3 / 64π

⇒ h = 2100/64π

⇒ h = 10.4 cm (rounded to 1 decimal place)
