Given tw circles, circle A with a radius of 3 in. and circle B with a radius of 12 in. find the ratio of the circumfrence of the smaller circle to the larger circle

1 : 4

Step-by-step explanation:

Circumference of the first one: 3 * 2 * π = 6π.

Circumference of the second one: 12 * 2 * π = 24π

Ratio: 6π:24π

divide both sides by 6π

1: 4

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

1; 35 is the ratio
