Question

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

Answer 1

B.

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

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 )
