Answer:
x = -3 or x = 3
Step-by-step explanation:
Subtract 9 from both sides.
x^2 - 9 = 0
Factor the left side. There is no common factor of the terms. It is a binomial which is the difference of two squares, so it factors into the product of a sum and a difference.
(x + 3)(x - 3) = 0
Set each factor equal to zero.
x + 3 = 0 or x - 3 = 0
Solve each equation.
x = -3 or x = 3

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
