A cone with a radius 2 units is shown below. Its volume is 29 cubic units. Find the height of the cone
rusak2 [61]

Answer:

The height of the cone is 6.9\ units

Step-by-step explanation:

we know that

The volume of the cone is equal to

V=\frac{1}{3}Bh

where

B is the area of the circular base of the cone

h is the height of the cone

In this problem we have

V=29\ units^{3}

r=2\ units

<em>Find the area of the base B</em>

B=\pi r^{2}

substitute the value of r

B=\pi (2)^{2}=4 \pi\ units^{2}

<em>Find the height of the cone</em>

29=\frac{1}{3}(4 \pi)h

h=29*3/(4 \pi)

assume \pi=3.14

h=29*3/(4*3.14)=6.9\ units
