Answer:
whats the ?
Step-by-step explanation:
so ?????????????????????????
We will use the following two facts:
1) Since ABCO is a rectangle, the two diagonals AC and OB are the same length
2) Since O is the center of the circle and B is a point on the circumference, OB is a radius of the circle.
We can compute the length of AC, since we know the length of OA and OC: in fact, OAC is a right triangle of which we know the two legs. So, we have
Invoking the point (1), we can deduce that
The area of a circle is given by the following formula:
And by point (2), we know that OB is a radius, so we have
if the guppies are doubling, that means whatever they were yesterday, today is 100% more, so the rate of growth is 100%.
