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

Olegator [25]

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) $V_{B}$ :

Volume of the cone:

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

Volume of the gum ball:

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

Answer: Individuals can help in the earthquake disaster by 3 rules. The first rule is looking out for there neighbor if they see that they are stuck within the rubble of the earthquake .

igomit [66]

Answer:

B. greater than

Explanation:

Air pressure decreases as the altitude increases.

Air pressure increases as the altitude decreases.

This means that if the air pressure of Denver, Colorado, at an altitude of about 5,000 feet above sea level, is 840mb, the sea-level pressure reported for Denver will be greater than 840 mbb.
