A cylinder is filled with 900 liters of water.find the area of its base if height of cylinder is 20dm.

Lisa [10]

The formula of the volume of a cylinder:

$V=\pi r^2H\\\\where:\\\\r-a\ radius\\H-a\ height\\\pi r^2-an\ area\ of\ base$

We have:

$V=900\ liters\\1L=1dm^3\ therefore\ V=900L=900dm^3$

and

$H=20\ dm$

substitute:

$\pi r^2\cdot20=900\ \ \ |:20\\\\\pi r^2=45\ dm^2$

Answer: The area of a base of the cylinder is equal 45 dm².

Answer:

$\frac{31}{6} + \frac{22}{3}I \leq 60$

Step-by-step explanation:

I have a 60-minute free trial of the game. It takes $5\frac{1}{6}$ i.e. $\frac{31}{6}$ minutes to set up the game and $7\frac{1}{3}$ i.e. $\frac{22}{3}$ minutes to play each level.

If I am able to play up to I number of levels within this 60 minutes, then we can write the inequality that gives the maximum number of level that I can play will be given by $\frac{31}{6} + \frac{22}{3}I \leq 60$ . (Answer)
