To determine the area if the circle, you must know the diameter or the radius of a circle.

If you know the radius of a circle, use this as your formula. Remember: Pi (the greek symbol thingy) is equal to 3.1415. (A is equal to area of the circle and r represents the radius)
a = \pi {r}^{2}
If you know the diameter, just divide the diameter to get the radius then use the same equation.

3.14*r^2

R stands for radius.

So if you are given that the diameter of a circle is 10 feet, we know the radius is half the diameter. So the radius is 5. So the equation is going to be 3.14*5^2 so the area would be about 78.54 feet

The median is the same as the ______________.
Ilia_Sergeevich [38]

Answer: Option A

The median is the same as the _ Second quartile_.

Step-by-step explanation:

Given a series of data ordered from least to greatest, the median is the value that is in the center.

That is, the median represents the value that divides 50% of the data.

In the same way, the first quartile Q_1 is the value that divides 25% of the data and the third quartile Q_3 is the value that divides 75% of the data.

The second quartile Q_2 is the number that divides 50% of the data.

Then notice that the second quartile is equal to the median

Then te answer is the option A.
