Answer 1

Step-by-step explanation:

2) Ratio of the length of the radius of an elliptical funnel and an elliptical cone=3:4

r1:r2=3:4

Let they be r1=3x and r2=4x

ratio of their heights=2:3

h1:h2=2:3

Let they be h1=2y and h2=3y

The volume of a cylinder =πr²h

=>πr²1h1

=>π(3x)²(2y)

=>V1=18πx²y cubic units

and the volume of a cone=πr²h/3

=>V2=πr²2h2/3 c.units

=>V2=π(4x)²(3y)/3

=>V2=16πx²y cubic units

Now their ratio=V1:V2

=>18πx²y:16πx²y

=>18:16

= 9:8

The ratio of their volumes =9:8

1)The ratio of capital investment of A,B,C =1/6:1/5:1/4

=>10:12:15

Let they be 10x,12x,15x

Capital of A=10x

Capital of B=12x

Capital of C=15x

Total profit at the end of year=3700

Total parts 10x+12x+15x=37x

37x parts=3700

1 part=3700/37

=>1 part=100

Now share of A=10×100=1000

Share of B=12×100=1200

Share of C=15×100=1500
