Question

let the volume of a solid right cylinder be v whose height is equal to the diameter of its base. a right solid cone of the same height is set on one plane face of the cylinder, both having the same base. if v is the volume of the resulting solid find v':v.​

Answer 1

a : b : b

b' : b' : c *

Now multiply the numbers in the columns like this —

ab' : bb': bc

So in this way, the answer to the question is 5*4 : 9*4 : 9*7 = 20:36:63

Or another method

Let a=5x

a=5x . Then, b=9x

b=9x . Now, let c=kx

c=kx . We need to find k

k.

b:c=4:7

b:c=4:7

⇒9x:kx=4:7

⇒9x:kx=4:7

⇒9:k=4:7

⇒9:k=4:7

⇒k=63/4

⇒k=63/4

⇒a:b:c=5:9:63/4=20:36:63
