The circumference of any circle is (pi) x (the diameter of the circle).
The problem gives you both numbers, so all you have to do is multiply them.
Circumference = (pi) x (diameter) = (3.14) x (21cm) = <em>65.94 cm .</em>
No because if that happened they wouldn’t be able to do it again so yeah
answer for this question is 4 x^ 3 Y ^4 root x
The answer is D: 180 degrees counterclockwise
