For any circle, which ratio is equal to the number π? select all that apply.
a.
circumference
diameter
b.
circumference
radius
c.
circumference
2 times radius
d.
radius
diameter
circumference
e.
f. area squared

circumference - diameter

circumference - 2 times radius

area - radius squared

Step-by-step explanation:

we know that

The circumference of a circle is equal to

or  

where

D is the diameter and r is the radius

therefore

 or

The number pi is the ratio circumference - diameter or is the ratio circumference - 2 times radius

The area of the circle is equal to

therefore

The number pi is the ratio Area - radius squared

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to

put in or use mine

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
