Whats the Diameter? I really need help understanding this

1.8 in.

Step-by-step explanation:

Hi there!

1) Determine the radius of the base

where r is the radius of the base and h is the height of the cone

Plug in the known values (h=4.2, V=3.6)

Isolate r; divide both sides by 4.2

Multiply both sides by 3

Divide both sides by π

Take the square root of both sides

2) Determine the diameter

Now that we have the radius, to find the diameter, multiply r by 2:

Therefore, the diameter is 1.8 in. when rounded to the nearest tenth.

I hope this helps!
