Find the circumference of each circle from the given radius or diameter. 1. Radius = 4m, diameter = 8 m

2. Diameter = 12ft, radius = 5ft

3. Diameter =6cm, radius = 3.2 cm

4. Diameter = 7.5 m , radius = 2.8 m

5. Radius = 8yd, diameter = 13yd

Let f(x)=2x and g(x)=2x. graph the functions on the same coordinate plane. what are the solutions to the equation f(x)=g(x) ?me asap

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
