What is the diameter of a circle with a 66 inch circumference??

1 answer:

6 0

$C = 2\pi r\\\\\frac{C}{2\pi } = \frac{2\pi r }{2\pi } \\\\\frac{C}{2\pi } = r\\\\\\\frac{66}{2\pi } = r\\\\21.01 = r$

Therefore, the diameter of the circle is about 21.01 in.

Answer:2 1/2 + 1/3 = 5/2 + 1/3 = 15/6 + 2/6 = 17/6 cup

(2/6)/(17/6) = (2/6)(6/17) = 2/17 (two parts in 17), or 11.8%

1 2/3 + 1/4 = 5/3 + 1/4 = 20/12 + 3/12 = 23/12 cup

(3/12)/(23/12) = (3/12)(12/23) = 3/23 (three parts in 23), or 13.04%
