Answer:
36 (Fill 3 in the blank)
Step-by-step explanation:
Given:
Volume of a cylinder = 324 π
Height = 9 cm
The formula to find the volume of a cylinder = Base area * height.
Base is a circle. So the area of a circle = πr^2
Volume of the cylindrical pillar = πr^2 h
324 π = πr^2 . 9
πr^2 = 324 π /9
πr^2 = 36 π
The area of the base = 36 π
Thank you.
Answer:
5 because 20 percent in a fraction is 1/5 so you would just divide 25 by 5. Or you could do 25 times .2 and your answer is still 5.
Step-by-step explanation:
In order to find the answer of the given problem above, we need to make the solution below:
Given: 2/3 of an hour = practice each day
2/3 of an hour is equivalent to 40 minutes
And per week, there are 7 days. So we will multiply 40 minutes by 7, and the result is 280 minutes. Since there are 60 minutes in an hour, we divide 280 by 60 and we get 4.67 hours. Therefore, each week, you would get 4.67 hours of practice on playing a musical instrument.
