Answer:
Step-by-step explanation:
one circle, lets name it x, Circumference(x)=2*3.14*r= 3.14*d, where d is the diameter
C=2*11*3.14
circle y= Circumference(y)=3.14*2*4
ratio of the radii
C(x)/C(y)=(2*11*3.14)/(2*4*3.14)=11/4= 2 3/4

Answer:
A
Step-by-step explanation:
A parabola opening up will have a positive value for the a value in ax^2+bx+c form. Also, the larger the absolute value of the a value, the more narrow the parabola will appear.
