Answer: 11.15 in^{3}

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 V_{C} and the volume of the buble gum ball (a sphere) V_{B}:

<u>Volume of the cone:</u>

V_{C}=\frac{\pi R^{2}h}{3} (1)

Where:

R=1.75 in is the radius of the cone

h=3.5 in is the height of the cone

V_{C}=\frac{\pi (1.75 in)^{2}3.5 in}{3} (2)

V_{C}=11.22 in^{3} (3) This is the volume of the cone

<u>Volume of the gum ball:</u>

V_{B}=\frac{4\pi r^{3}}{3} (4)

Where:

r=\frac{0.5 in}{2}=0.25 in is the radius of the sphere (half the diameter)

V_{B}=\frac{4\pi (0.25 in)^{3}}{3} (5)

V_{B}=0.065 in^{3} (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):

V_{C}-V_{B}=11.22 in^{3}-0.065 in^{3} (7)

Finally:

V_{C}-V_{B}=11.15 in^{3} (8)

Musya8 [376]

A continental volcanic arc created due to the subduction of the Nazca Plate beneath the South American Plate has lead to the formation of the Andes mountains and Cotopaxi Volcano.

Option B

<u>Explanation</u>:

Mountains and volcano are mainly created due to the movement of plate depending on type of plate when plates of converging nature the for folds which make them create mountainous topography or during subduction zone where the Andes mountain Cotopaxi volcano was created their reason for their formation was the movement of Nazca plate beneath the American plate which led to the mountainous formation along the volcanic formation. The movement in plates can really make all the difference in topography and that’s how all the mountains are formed by it Himalaya or any other mountain.
