Question

28.
Diameters of two cylinders are in ratio of 4:5 and with Same height. Find the
ratio of their volume.​

Answer 1

Answer:

16:25

Step-by-step explanation:

Sicnce diameter in ratio 4:5 we can say radius are also in ratio 4:5. let radius are r1 and r2 respectively, so r1:r2 = 4:5. now lets volumes foof cylinders are v1 and v2. so v1:v2 = πr₁²h:πr₂²h. so v1:v2 = r₁²:r₂².

now r1:r2 = 4:5, so r₁²:r₂² = 16:25.

so v1:v2 = 16:25.
