Answer:
Both/Neither.
Step-by-step explanation:
For the circle, the area is π(6)^2= 36π. 3/4 of that is 27π. Now, for the ring, area of outer circle is 36π. The area of inner circle is 9π. So, area of ring is 27π. That means, both will take the same amount of paint.

Answer: is x=4
Simplifying
5x + 4 = 24
Reorder the terms:
4 + 5x = 24
Solving
4 + 5x = 24
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-4' to each side of the equation.
4 + -4 + 5x = 24 + -4
Combine like terms: 4 + -4 = 0
0 + 5x = 24 + -4
5x = 24 + -4
Combine like terms: 24 + -4 = 20
5x = 20
Divide each side by '5'.
x = 4
Simplifying
x = 4
