Answer:
20:27
Step-by-step explanation:
there are 2 cylinders...
radius of first cylinder = 2x
r of second cylinder= 3x
height of first cylinder = 5y
height of second cylinder = 3y
ratio of volumes between them
= (2πr^2h)/(2πr^2h)
= {2x 22/7 (2x)^2 (5y)} / {2x22/7 (3x)^2(3y)}
( 2, 22/7 cancelled by each other)
= 4x^2 (5y) / 9x^2 (3y)
(x^2 and y cancelled by each other)
= (4x 5)/ (9x3)
= 20/ 27
ratio between them is 20:27
mark me as brainliest plz❤️❤️
Answer:
The radii of two cylinders are in the ratio 2:3 and their heights are in the ratio 5:3 . The ratio of their volumes is. Step by step solution by experts to help you in doubt clearance & scoring excellent marks in exams. =π×(2r)2×5hπ×(3r)2×3h=2027.
Step-by-step explanation:
Correct option is
D
20:27
As radii of two cylinder in in ratio of 2:3
So radius of 1st cylinder=2r
radius of 2st cylinder=3r
heights are in the ratio 5:3.
height of 1st cylinder=5h
height of 2st cylinder=3h
ratio of volume=volume of 1st cylinder/volume of 2nd cylinder
V=Π(2r)
2
∗5h/Π(3r)
2
∗3h
V=20rh/27rh
V=20/27
