+55 number 1 In the diagram below, the area of is 60. What is the length of side ?
Number 2 Two circles are drawn below. The diameter of the smaller circle is a radius of the larger circle. What is the ratio of the smaller circle's circumference to the larger circle's circumference?
Give your answer in fully simplified form. It should look like "x:y", where x and y are replaced by integers.
+37146 Please clarify your question the area of WHAT = 60?
2) circumference = pi * d
larger circle diameter = d circumference = pi * d
smaller circle diameter = 1/2 d circumference = pi * 1/2 d
ratio s/m = pi * 1/2d / pi * d = 1/2 / 1 = .5 / 1 = 1/2
