An orange is 9 cm in diameter. If 2/9 of it is juice, how much can you get from 7 such oranges. Assume that the orange is a sphere. Two-thirds of the juice is poured into a cylindrical container 14 cm high and diameter 7 cm. How many ice-
cubes, each of sides 3 cm, can be added before the juice begins to overflow?

Step-by-step explanation:

Volume of each orange:

Volume of juice from 7 oranges:

Juice poured into a container:

Volume of the container:

Empty part of the container after juice is poured:

Volume of each ice cube:

Number of ice cubes to fill the containers' volume:

5 ice cubes can be added, the juice will overflow if 6th ice cube is added

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).

good luck on your studies! : )
