What is the range of the following data set 13,17,18,15,12,21,10 a.3 b.6 c.8 d.11

Hello!

The range is the lowest number subtracted by the highest

The highest number is 21

The lowest is 10

21 - 10 = 11

The answer is D.11

Hope this helps!

Hello there, and thank you for posting your question here on

When finding the area of a circle, we have to use the formula A = πr².

But we don't know what the radius is, but we know what the diameter is.

The radius is half of the diameter.

So to find do the area, we need to divide the known diameter, (250) by 2.

250 / 2 ===> 125.

Now we have A = π125².

Square 125, and then multiply that by pi, or 3.14

125 * 125 (125²) ===> 15625.

Multiply 15625 by 3.14 (pi)

15625 * 3.14 ≈ 49062.5

Your answer is B.

Hope this helped!! ☺♥
