Best ResponseYou've already chosen the best response.2Gabby you missed the Pi there, that's very important =)

Best ResponseYou've already chosen the best response.2So circumference = 2*radius * pi. And diameter = 2 * radius. So circumference also = diameter * pi Can you solve it now?

Best ResponseYou've already chosen the best response.2So let's look at (a). If d = 40. What is d * pi? Does that equal 20 * pi?

Best ResponseYou've already chosen the best response.2Very good. Can you do the same for (b) now?

Best ResponseYou've already chosen the best response.0b is not correct either so now its just C and D

Best ResponseYou've already chosen the best response.0because it needs a radius

Best ResponseYou've already chosen the best response.2b is correct. let's go through it carefully. Remember, diameter is radius * 2. So you must multiply that 10 by 2.

Best ResponseYou've already chosen the best response.2diameter can be converted to radius (d = 2*r). Also, radius can be converted to diameter (r = d/2)
