A cone is placed inside a cylinder. The cone has half the radius of the cylinder, but the height of each figure is the same. The

Answer:

$\frac{11}{12}\pi r^{2}h\ units^{3}$

Step-by-step explanation:

we know that

<em>Te volume of the cone is equal to</em>

$V=\frac{1}{3}\pi r^{2}h$

we have

$r=(r/2)\ units$

substitute

$V=\frac{1}{3}\pi (r/2)^{2}h$

$V=\frac{1}{12}\pi r^{2}h$

<em>Te volume of the cylinder is equal to</em>

$V=\pi r^{2}h$

we know that

To find the volume of the space remaining in the cylinder after the cone is placed inside it, subtract the volume of the cone from the volume of cylinder

$\pi r^{2}h-\frac{1}{12}\pi r^{2}h=\frac{11}{12}\pi r^{2}h\ units^{3}$

I am an odd number, I am less than 100, the sum of my digits is 12, I am a multiple of 15. What number am I

vova2212 [387]

The answer is 3
Think of two odd numbers (1,3,5,7,or 9) that add up to twelve.
The number as one has to be a multiple of 15 (15 should be able to be multiplied by any number to get to that odd number).
