The radius of the cone id 1.75 inches an the height id 3.5 inches. If the diameter of the bubble gum ball is 0.5 inches what is the closest approximation of the volume of the cone

Explanation:

We need to know the volume of the cone that can be filled with bubble gum ball, but firstly we need to calculate the volume of the cone and the volume of the buble gum ball (a sphere) :

Volume of the cone:

(1)

Where:

is the radius of the cone

is the height of the cone

(2)

(3) This is the volume of the cone

Volume of the gum ball:

(4)

Where:

is the radius of the sphere (half the diameter)

(5)

(6) This is the volume of the gum ball

Know we are able to find the closest approximation of the volume of the cone that can be filled with bubble gum ball, by calculating the difference or substracting (6) from (3):

(7)

Finally:

(8)

the precambrian aged rocks could be found in australia. australia is a region that has a lot of ancient civilization history from million years ago. in this region, there are a lot of recognizable fossils buried in its land which is considered a precambrian-aged rocks
