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)

During an El Niño–Southern Oscillation event, which of the following best describes conditions in the eastern part of the tropic

miss Akunina [59]

Answer:

High sea surface temperature and High rainfall

Explanation:

El Niño is a pattern of climate that causes the unusual warming of surface waters in the eastern part of the tropical Pacific Ocean. It affects the temperature of the ocean and changes the strength and speed of its currents, coastal fisheries' health, and local weather from South America to Australia and beyond.

It begins when warm water in the western part of the tropical Pacific Ocean moves toward the eastern part of the tropical Pacific Ocean along the equator. Usually, warm water pools near Indonesia and the Philippines, but during El Niño, the warmest water of the Pacific Ocean assembles at the eastern part of the tropical pacific ocean.

Moreover, trade winds weaken in the central and western part of the tropical Pacific Ocean that weaken the upwelling of nutrient-full cold water to cool warm surface water at the eastern tropical Pacific Ocean. This warm surface water of eastern part of tropical Pacific Ocean warms the atmosphere that empowers moisture-rich air to develop into thunderstorms.

In this way El Niño - Southern Oscillation Event causes the rise in temperature of sea surface and high rainfall at eastern part of the tropical Pacific Ocean.
