A cylindrical bowl of internal diameter 18cm and height 15cm is full of liquid . The whole liquid is to be filled in small cylindrical bottles of diameter 3cm and height 4cm . Each bottle is sold for Rs 5, find the amount earned
Answers
The total earning is ₹675
Given data :
Bowl's diameter = 18 cm
Height = 15 cm
Bottle's diameter = 3 cm
Height = 4 cm
Price = ₹ 5/piece
So,
Bowl's :
Radius = 18/2 = 9 cm
Volume = π × 9 × 9 × 15 = 1215π cm³
Bottle's :
Radius = 3/2 = 1.5 cm
Volume = π × 1.5 × 1.5 × 4 = 9π cm³
So,total number of bottle = (1215π / 9π) = 135
Total earnings = 135 × 5 = ₹675 (answer)
Answer:
answer is Rs.675
Step-by-step explanation:
internal diameter=18cm
so radius (R)=9cm
height of cylindrical bowl(H)=15cm
diameter of small cylindrical bottles=3cm
radius(r)=1.5 cm
height of small bottle(h)=4cm
let the no. of bottles needed to empty the liquid of the cylindrical bowl be x
volume of cylindrical bowl=x*volume of small bottle
=>22/7*R^2*H=x*22/7*r^2*h
=>22/7*9*9*15=x*22/7*1.5*1.5*4
=>135=x
no. of bottles =135
cost per bottle=Rs.5
amount earned=Rs.5*135=Rs.675.
