Question

height of a cylinder barral is 50 cm and radius of the base is 20cm Anurag started to fill the barrel with water, when it was empty by cylindrical mug . The diameter and height of the mug was 10 cm and 15 CM respectively. How many minimum number of mug will be required for the barrel to overflow?​

Answer 1

Answer:

DIMENSIONS OF CYLINDRICAL BARELL:

HIEGHT OF CYLINDER=50 cm.

RADIUS OF CYLINDER=20 cm.

DIMENSIONS OF MUG(CYLINDRICAL):

HIEGHT=15 cm.

DIAMETER=10 cm

RADIUS =D/2=10/2 cm=5 cm.

VOLUME OF CYLINDRICAL BARELL = VOLUME OF CYLINDRICAL MUG×N

(here,N means number of mugs required to empty the barell)

pi×R^2×H=pi×r^2×h×(N)

pi/pi×(20 cm)^2×50cm=(5cm)^2×15cm×N

20000cm^3=375cm^2×N

N=20000cm^3÷375cm^2

N=53.33 cm.
