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>
Bigger number is 3625 and smaller number is 3125
The appropriate response is B. The contend that there is no requirement for understudies to utilize a compass and straightedge, and every single geometric development ought to be finished utilizing a drawing program is the wrong explanation since the power to control drawing programs is just open in a few spots. Not everyone would have the capacity to learn geometry in light of the fact that not everyone can have power. Everyone on the planet would not have a similar opportunity to learn geometry if just drawing programs had the information that we have today.
