What is the approximate circumference of a circle that has a radius of 10 centimeters? (Use 3.14 for ). C=__ cm
2 answers:
Answer:
62.8
Step-by-step explanation:
Radius is 10, so the diameter is 20 (10x2)
20 x 3.14(pi)= 62.8
Answer:

Is this a riddle?? Or are you really doing this :-(
ANSWER :
The center-radius form of the circle equation is in the format (x – h)2 + (y – k)2 = r2, with the center being at the point (h, k) and the radius being "r". This form of the equation is helpful, since you can easily find the center and the radius.

Answer:
3:4
Step-by-step explanation:
(1/7)/(4/21) = (1/7)×(21/4) = 3/4 = 3:4
150 to 60. But the more commen why to do that were to simplify it.
