x=-300
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).
Wouldnt it be 4 im pretty sure i did the math right i hope this works can you answer mine?
Well you add 1/2 + 1/2 = 1 in
(1/2+1/2) + (1/2+1/2) + (1/2+1/2) + (1/2+1/2) + (1/2+1/2) + 1/2=
2 half inches per parentheses pairs which is 5 plus the 1/2 inch
( 11 half inches shown above)
