The diameter is 48 feet. The radius is half of the diameter, so it is 24 feet. The area can be found using the formula pi r ^ 2. So, the area is 576 pi
Answer:
150=
x, or 4(150)=x
Step-by-step explanation:
Let's use x to represent the total number of pages in the book.
If 150 is a quarter of the whole book, then 150 is equal to a quarter of x
150= .25(x)
We an go further and multiply both sides by 4 to cancel the .25
4(150)=x
We can finish solving and x=600 pages

There are 4 terms in this series
That's because the summation (Sigma) goes from 3 to 6 inclusive. So k takes on values of 3,4,5,6
You could use this summation formula
Formula
Sum = (a + L)n/2
Substitution
a is the first term.
k = 3 for the first term
a = -5k + 20
a = -5(3) + 20
a = -15 + 20
a = 5
For the last term k = 6
L = -5(6) + 20
L = -30 + 20
L = - 10
Sum
Sum = (5 - 10)*4/2
Sum = -5 * 2
Sum = -10

You may wonder how come the last term and the sum are the same. The reason to be found by figuring out the 4 terms and adding them together.
When k = 3, -5k + 20 = -15 + 20 = 5
When k = 4, -5k + 20 = -20 + 20 = 0
When k = 5, -5k + 20 = -25 + 20 = -5
When k = 6, -5k + 20 = -30 + 20 = -10
Sum = 5 + 0 - 5 - 10 = - 10
Conclusion.
It is an accident of the numbers.
Answer: - 10 = the Sum
Take 40 and multiply it by any number bigger than 2 then add 4.
124,164,204
A. multiply all the numbers together to find the possible outcomes
4 x 4 = 16
There are 16 different jacket-shirt outfits Ardell have.
They will not be the same color = 4 x 3
4 x 3 = 12
12/16 = 0.75, or a 75% chance they will not be the same color
hope this helps
