A Cone has a radius of 3 and a height of 5. solve.

Alexus [3.1K]

Assuming your looking for volume.

The following formula is used for calculating the volume (V) of a cone.

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

where r is the radius and h, the height.
Substitute r = 3 and h = 5 into the formula.

⇒ $V=\frac{\pi *3^{2} *&5}{3} =\frac{45*\pi }{3}$ ≈ $47.124$ $cubic$ $cm$
