Radius is half of the diameter.
So because the area of a circle is A= pi • r^2, to find the radius first, we have to change the equation to solve for r. Now it is, r= square root of A/pi. We plug in 1134.1. (Look at pic)
The diameter is 38
Answer:
10
Step-by-step explanation:
Let "a number" = x
4(x - 4) = 24
Isolate the x. First, divide 4 from both sides
(4(x -4))/4 = (24)/4
x - 4 = 6
Add 4 to both sides
x - 4 (+4) = 6 (+4)
x = 6 + 4
x = 10
10 is your answer for "a number"
You look for two good points on the graph, then you rise and run.( go up then move right or left)
1 modulo 9 is the set of numbers as follows:
(0(9) + 1), (1(9) + 1, ....)
which is:
1, 10, 19
All we have to do is divide 1000 by 9, and round down.
1000/9 = 111.111......
There are 111 numbers.
Now let us check our work.
the set is as follows:
(1,10,19, ....... (111)9 +1)
(1, 10, 19 ........ 1000)
We are within 1000.
Therefore, 111 of the 1000 smallest positive integers are congruent to 1 modulo 9.
