Question

The ratio of the circumference of two circles in 3:2. The radius of the smaller circle is 8 in. What is the radius of the larger circle?

Answer 1

If it’s a ratio of 3:2, it’s basically giving you two separate expressions, which are 3x and 2x. Use 8 for the smaller expression: 2x=8 and x=4. Plug in x to larger expression: 3(4)=12. Radius of larger circle is 12.
