The diameter of a circular pool is 18 feet. What is the approximate area of the pool?
A.
56.52 square feet
B.
113.04 square feet
C.
254.34 square feet
D.
1017.36 square feet
Answers
Answer 1
Answer:
The formula for the diametre of a circle is πr². This means we need to find the radius. The radius is half the diametre (9).
3.14 (9)² =
3.14 (81) =
254.34 square feet is your answer
3.14 (9)² =
3.14 (81) =
254.34 square feet is your answer

In order to get the total price, we need to figure out 7.5% of 21, then add that number to 21.
In order to get 7.5% of 21, we just multiply 21 by 0.075 (since 7.5% ind decimal form is 0.075)
%3D1.575)
Then, we add that number to 21.
The answer is 22.575, which we can round to $22.58.

-30/54 in simplest form:
First, we can start out by finding the greatest common factor (GCF) of the numerator (30) and the denominator (54). To do so, we will list the factors of each number, find the common ones and then the greatest.
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54
Look through both sets of factors. Which are the common factors? 1, 2, 3, and 6 are the common factors of 30 and 54. Now, we have the find the greatest common factor. Basically, which number has greater value out of 1, 2, 3, and 6? The GCF is 6.
Second, our last step is to divide the numerator (30) and denominator (54) by our recently found GCF which was 6. This will create a new fraction which is in simplest form.
Let's collect our new numerator and denominator and rewrite our brand new fraction in its simplest form.

distributive property is a(b+c)=ab+ac
it could be
8 is 'a' or
71 is 'a'
I prefer 71=a so
basically b+c=8
probably prefer positive so
some possible combls are
0 and 8
1 and 7
2 and 6
3 and 5
4 and 4
and the rest is just reverse
71(0+8)=71(0)+71(8)=0+568=568
71(1+7)=71(1)+71(7)=71+497=568
71(2+6)=71(2)+71(6)=142+426=568
71(3+5)=71(3)+71(5)=213+355=568
71(4+4)=71(4)+71(4)=284+284=568
