Question

A come has a height of 8cm and a diameter of 5 cm. Which of the following represents the volume of the cone

Answer 1

Answer:

C.

$V=\frac{1}{3}\pi(2.5)^{2}(8)$

Explanation:

Given:

Height of the cone(h) = 8 cm

Diameter of the cone(d) = 5 cm

Radius of the cone(r) = d/2 = 5/2 = 2.5 cm

Recall that the volume(V) of a cone can be determined using the below formula;

$V=\frac{1}{3}\pi r^2h$

If we go ahead and substitute the given values into the formula, we'll have;

$V=\frac{1}{3}\pi(2.5)^2(8)$
