Zion has a sink that is shaped like a half-sphere. The sink has a volume of 2500/3 π" i" "n" ^3. One day, his sink clogged. He has to use one of two cylindrical cups to scoop the water out of the sink. The sink is completely full when Zion begins scooping. (a) One cup has a diameter of 5 in. And a height of 8 in. How many cups of water must Zion scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number (round up). (b) One cup has a diameter of 7 in. And a height of 7 in. How many cups of water must he scoop out of the sink with this cup to empty it? Round the number of scoops to the nearest whole number (round up).

Answer is in the photo. I can't attach it here, but I've uploaded it to a file hosting. link below! Good Luck!

i think it is c, not positive though

step-by-step explanation:

"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).
