A circle has an area of 785 units squared and a circumference of 31.4 units. If the radius is 5 units, what can be said about the relationship
between the area and the circumference? (Use 3.14 for T.)
A.
The ratio of the area to the circumference is equal to the radius squared
B.
The ratio of the area to the circumference is equal to half
C.
The ratio of the area to the circumference is equal to the square root of the radius
D.
The ratio of the area to the circumference is equal to twice the radius

B.

The ratio of the area to the circumference is equal to half

Step-by-step explanation:

hello :

the area is: A= πr²   and  the circumference is : P= 2 πr   r : the radius

so : A/P =πr² /2 πr   = r/2   (simplify by πr )

practice. practice. practice.

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
