an orange is 7 cm in diameter,if 2/9 of it is made up of juice how much juice can you get from squeezing 7 similar such oranges?
Volume of orange is V = pi.D^2/4
V = pi*(7)^2/4 = 49pi/4
2/9 of that volume is juice, i.e.
Vj = 2V/9 = 49pi/18
Total volume from 7 such oranges is Vt, where
Vt = 7Vj = 343pi/18
Volume = 343pi/18 cm^3 = 59.86 cm^3
