Answer:

Step-by-step explanation:
the bar above 36 means that the digits 36 are being repeated
we require 2 equations with the repeating digits placed after the decimal point.
let x = 0.13636.. ( multiply both sides by 10 and 1000 )
10x = 1.3636... (1)
1000x = 136.3636... (2)
subtract (1) from (2) thus eliminating the repeating digits
990x = 135 ( divide both sides by 990 )
x =
=
← in simplest form
1.4 gallons for each rose bush. Divide the amount of rose bushes (7) by how many gallons of water she has (5). 7÷5=1.4 The answer is 1.4 gallons.
I believe it’s translation
we can use
volume of cone formula

where
r' is radius of cone
h' is height of cone
we are given
The radius of the cone is half the radius of the cylinder
so,

The height of the cone is equal to the radius of the cylinder
so,

now, we can plug values into formula
we get

we can simplify it

so, option-C.........Answer
