Which is an equivalent equation solved for r? the circumference of a circle can be found using the formula c = 2πr. r=cπ r=c(2π) r= c over 2π r= 2π over c

r= C over 2π

Step-by-step explanation:

C =  2πr

To solve for r, divide each side by  2π

C/  2π =  2πr/  2π

C/  2π =  r

r= C over 2π or

Step-by-step explanation:

Formula to find the circumference of a circle is given by :-

, where r is the radius of the circle .

To find the formula for r , we need to divide both sides by , we get

Hence, an equivalent equation solved for r will be :-

i.e. r= C over 2π

62.8 yards.

Step-by-step explanation:

The formula to find the circumference of a circle using just the diameter is C = πd, with c being the circumference and d being the diameter. 20 multiplied by 3.14 is equal to 62.8, and the unit is simply yards because you are measuring length rather than area.
