Disclamer: the following is confusing but I will transcribe what is going on in my head
3:4, 3+4=7
4:5, 4+5=9
hm
we can do fractions
3:4, 4 units is yellow
4/7 of all is yellow
4:5, 5/9 of all is yellow
all end is all-9
yellow intial=6+yellowfinal
yellowinitial=(4/7)all
(let's say all=x)
yi=(4/7)x
final=(5/9)(x-9)
yi=6+yf
(4/7)x=6+(5/9)(x-9)
times both sides by 63
36x=378+35(x-9)
distribute
36x=378+35x-315
36x=35x+63
minus 35x both sides
x=63
yellow=(4/7)(x)
yellow=(4/7)(63)
yellow=36
there wer 36 originally
Answer:
1018.28
Given -
Diameter of cone = 18 cm
To get the radius divide it by 2 -
Radius, r = 18/2 = 9
height, h = 12 cm
To find -
Volume of cone.
Solution -
Volume = 1/3 hπr²
→ V = 1/3 18 × 22/7 × 9 × 9
→ V = 7128/7
→ V = 1018.28
Therefore, the volume of the cone is 1018.28.
