The circumference of circle b is 48. the circumference of circle a is 12. how many times greater is the area of circle b to the area of circle a

Circumference = 2(pi)(radius)

Circle 1: 48=2(pi)(radius)
              24/pi = radius

Circle 2: 12 = 2(pi)(radius)
                6/pi = radius

Area = (pi)(radius)^2

Circle 1: A = (pi) (24/pi)^2
                  = 576 / pi

Circle 2:  A = (pi) (12/pi)^2
                  = 144 / pi

576/144 = 4 times greater

You have 2 sides that are 2 cms and you have 6 sides that are 1/2 cm and you have 4 sides that are 1 cm. the smallest sides are 1/2 the medium sized sides are 1 and the smallest are 1/2. so to find the perimeter you have to add them all up together so your answer will be 11 cm's

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
