For any circle, which ratio is equal to the number π? Select all that apply. A. circumferencediameter B. circumferenceradius C. circumference2 times radius D. radiusdiametercircumference E. F.area squared
Accepted Solution
A:
Answer:circumference - diametercircumference - 2 times radiusarea - radius squaredStep-by-step explanation:we know thatThe circumference of a circle is equal to[tex]C=\pi D[/tex] or [tex]C=2\pi r[/tex]whereD is the diameter and r is the radiustherefore[tex]\pi =\frac{C}{D}[/tex] or [tex]\pi =\frac{C}{2r}[/tex]The number pi is the ratio circumference - diameter or is the ratio circumference - 2 times radius The area of the circle is equal to[tex]A=\pi r^{2}[/tex]therefore[tex]\pi =\frac{A}{r^{2} }[/tex]The number pi is the ratio Area - radius squared
