Question

Find the radius of a cone with volume 199.23 cm3 and height 9 cm.

Answer 1

use the formula in finding the volume of a cone

Answer 2

The volume of a cone is given as\[(1/3)\pi*r^2*h\] . Use your 2 pieces of information and the formula to solve for r.

Answer 3

no i am trying to find the radius
not volume

Answer 4

You are given the volume and the height in the question. If you plug those numbers in, you've got \[199.23=(1/3)\pi*r^2*9\] Do you see where 199.23 was plugged in for V and 9 was plugged into h (height)?

Now you just need to solve for the only variable left in the equation, r, which is the radius.
