Step-by-step explanation:
we know that
The area of the base of a cylinder is given by the formula

where
r is the radius of the circular base
If the radius is doubled
then

The new base area is


so

therefore
The new area of the base is 4 times the area of the original base

Answer:

Step-by-step explanation:
Note the bar above 1 means 1 is repeating , that is
0.111..
We require 2 equations with the repeating digit placed after the decimal point
let x = 0.111.... (1) Multiply both sides by 10
10x = 1.111... (2)
Subtract (1) from (2) thus eliminating the repeating digit
9x = 1 ( divide both sides by 9 )
x =
