Question

14. 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

Answer:

here is your answer mate:)

Explanation:

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

hope it's helpful to you!
