Mary serves juice to her guests in cylindrical cups of radius 7 cm having a height of 10 cm. If she serves 25 cups, she will need
Given,
Radius of cylindrical cup, r = 7 cm
Height of cylindrical cup, h = 10 cm
We know, volume of a cylinder=πr2h
So, putting values we get:
Volume of 1 cylindrical glass=227×72×10
=1540 cm3
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 cm3
