The approximate radius of the cone’s base unite. the approximate volume of the cone is __ cubic units

Approximate radius of cone's base is 21 units

Approximate volume of the cone is 9702 cubic units

Step-by-step explanation:

1. Area of the base (which is a circle) is given as 1386. We know that area of a circle is given as

Equating this to 1386 and solving for :

is approximately 21 units

2. Volume of Cone is given by

Given radius and height are equal and they are 21 units each, plugging in the values we get:

Volume of Cone =

Volume of Cone is approximately 9702 cubic units.

an altitude of 15,000 feet
