The number of square units in the area of circle o is equal to 16 times the number of units in its circumference which of the following are diameters of circles that could fit completely inside circle 0? indicate all such diameters □

a. 25
b. 36
c. 42
d. 48
e. 54
f. 66
g. 70

A,B,C,D,E

Step-by-step explanation:

the relationship given between the area and circumference is:

Using the formulas for area and circumference of the circle

solving:

convert this into diameter

: Diameter of circle O

Now, the question is asking us to select all such diameters that can fit completely inside this circle O

So, all we need to do is just select all circles that have a diameter less than 64 units. All such circles that have a diameter less than 64 units will completely fit inside the circle O.

Hence, the circles that fit inside circle O are: A,B,C,D,E

If you get 0=0 there are infinite solutions because the lines are the same line

Choice D
