A cone's circular base has a diameter of 8 feet. The volume of the cone is 279 cubic feet. What is the approximate height of the cone?

Given Data :

Diameter = 8 ft

Volume of Cone = 279 ft³

Formula for Cone

____________________________________

As we know radius is diameter/2

Radius = 8/2 = 4 ft

Now, putting the values in the formula we get

Now, putting the value of volume which is 279 ft we get

After approximating we will get the value as 16.65 ft

Hence, the correct answer is the first option i.e 16.65 ft

2(5) = 10 feet

Step-by-step explanation:

1) 4.6x + 5x + 6x + 2x = 17.6x

2) 17.6x = 88

x = 5

Plug 5 for x in 2x.

2(5) = 10.

Hope that helps! :)
