Question

the base radius of two cylinders are in the ratio 2:3 and their height are in the ratio 5:4 a) what is the ratio of their volume b). the volume of first cylinder is 720cm sq then what is the volume of second.​

Answer 1

Answer:

(a) 5:9

Step-by-step explanation:

(a)let the base radius of tbe first cylinder be 2 and of 2nd cylinder be 3 and height of 1st be 5 and of 2nd be 4

volume of 1st cylinder / volume of 2nd cylinder

= Π r²h/Πr²h

= r²h/r²h

= 2²×5/3²×4

=5/9

=5:9
