If an orange traffic cone has a diameter of 10 in. and a height of 28 in. what is the volume of the cone?
e-lub [12.9K]

Answer:

\large\boxed{V=\dfrac{700\pi}{3}\ in^3\approx732.67\ in^3}

Step-by-step explanation:

The formula of a volume of a cone:

V=\dfrac{1}{3}\pi r^2H

<em>r</em><em> - radius</em>

<em>H</em><em> - height</em>

We have the diameter <em>2r = 10in → r = 5in</em>, and the height <em>H = 28in.</em>

Substitute:

V=\dfrac{1}{3}\pi(5^2)(28)=\dfrac{1}{3}\pi(25)(28)=\dfrac{700\pi}{3}\ in^3

\pi\approx3.14\to V\approx\dfrac{(700)(3.14)}{3}\approx732.67\ in^3
