Numbers starting with a 1 and followed by only 0s (such 10, 100, 1,000,10,000, and so forth) are called powers of ten, and they're easy to represent as "exponents". Powers of ten are the result of multiplying 10 times itself any number of times.

Is change in math always represented as a positive number even when its negative?

beks73 [17]

I think you mean like a number decreasing at a percentage. Yea it’s gonna be positive cause like it’s a number but then it’s probably gonna say decreasing making it negative or increasing making it positive. I’m pretty sure, correct if I’m wrong.

The diameter of a circle is 14 in. Find its area in terms of <br> π<br> π.

maksim [4K]

Answer:

49π in²

Step-by-step explanation:

Step 1: Find the radius.

To find radius given diameter, just divide the diameter by 2: $\frac{14}{2}$
14/2 = 7, so the radius is 7.

Step 2: Apply area of circle formula.

The formula to find the area of a circle is πr², where r = radius.
Now, plug in the value of r: π(11)².

Step 3: Simplify.

π(11)²
π(121)
121π

Since we're finding the area in terms of pi, we don't have to multiply 121 by pi, so the answer is 49π in².
