Answer:quadrupled
Step-by-step explanation:
If the radius of a circle is doubled, the area of the circle will be quadrupled and the circumference will also be doubled. This makes sense because the area of a circle is directly proportional to the square of the radius of the circle (if the radius of a circle is increased x times, its area will be increased to x^2 times the original area), whereas the circumference is proportional to the size of the radius (if the radius of a circle is increased x times, its circumference will increase x times).

Answer:
a = 1/8
Step-by-step explanation:
2 is the x value and y =.5
Substitute this into the equation
f(x) = ax^2
.5 = a(2)^2
.5 = a 4
Divide each side by 4
.5/4 = 4a/4
1/8 = a
