Question

please solve #5 and #6 question.​

Answer 1

5).Ratio of thier volumes=3600/5040

πr²h:πr²h'=5:7

h:h'=5:7

6).let the hieght of first cone (h1)=h

So,the hieght of second cone(h2)=2h

radius of both cones are r and r' respectively

ratio of thier volumes=2:3

1/3πr²(h1):1/3πr'²(h2)=2:3

1/3πr²h:1/3πr'²2h=2:3

r²:2r'²=2:3

r²/r'²=4/3

r/r'=2/√3

r:r'=2:√3
