Answer:
706.50 cubic cm.
Step-by-step explanation:
Given that a cylinder shaped juice pitcher has a diameter of 12 cm and a height of 25 cm.
We are to find out the t volume of juice does the pitcher contain when it is 25% full. 3.14 is to be used for pi.
Volume of the cylinder = 
When it is 25% full the volume would be 1/4 of the full volume
=
cubic cm
So volume when 25% full is
706.50 cubic cm.
You have to use the Pythagorean theorem a squared plus b squared is c squared so 13 squared plus 18 squared equals c squared. 13x13=169 18x18=324 169+324=493 so c squared is 493 to get c you square root 493 which equals 22.2 so the diagonal, c, is 22.2 centimeters long
