Answer:
The area is 176.6
Step-by-step explanation:
The formula for the area of a circle is "πr²"
This means you square the radius, and multiply it by pi.
Our diameter is 15, and the radius is half of the diameter.
15 ÷ 2 = 7.5
Next, we square the radius. (7.5)
Let's fill it into the formula.
π7.5²
After squaring, it's this:
π56.25
In your question, pi is 3.14, so let's replace that.
(3.14)56.25
After multiplying we get 176.625, after we round, we get 176.6
176.6 is the area.

The unit price of the disk is $0.549
<h3>Unit price of goods</h3>
The unit price of goods are the price of one portion of the goods in question.
From the given question, a package of blank compact discs on sale at 10 for $5.49, this can be expressed as;
10 disc = $5.49
The unit price of the disc is the price of just one of the disc. The unit price is expressed as;
1 disc = x
Find the ratio
10/1 = 5.49/x
Cross multiply
10x = 5.49
Divide both sides by 10
10x/10 = 5.49/10
x = $0.549
Hence the unit price of the disk is $0.549

Answer:
1/6^3
Step-by-step explanation:
The applicable rules of exponents are ...
a^-b = 1/a^b
(a^b)(a^c) = a^(b+c)
__
Your expression can be simplified as follows:
_____
<em>Additional comment</em>
If you think of an exponent as signifying repeated multiplication, the rules of exponents may be easier to remember. The exponent tells you how many times the base is a factor in the product.
Consider multiplication:
Consider division:
This may help you see that a positive exponent in the denominator is equivalent to a negative exponent in the numerator (and vice versa).
