Mary serves juice to her guests in cylindrical cups of radius 7 in having a height of 10 in. If she serves 25 cups, she will need
Given,
Radius of cylindrical cup, r = 7 in
Height of cylindrical cup, h = 10 in
We know, volume of a cylinder=πr2h
So, putting values we get:
Volume of 1 cylindrical glass=227×72×10
=1540 in3
Now, Mary has served 25 juice cups.
So, total volume of juice Mary needs = Volume of each cup × total number of cups
=1540×25=38500 in3
