An addition sign between 978 and 842 would make the equation true!
Area = pi*r^2
Circumference = 2pi*r
Step 1: find the radius from area
81pi=pi*r^2
81=r^2
9=r
Step 2: plug in radius to the circumference equation
Circumference = 2pi*r
18pi is the answer, otherwise know as 56.52 as well.
Answer:
Equation that represents the line passing through the point -3, -1 with a slope of 4 is

Step-by-step explanation:
Equation of line in point slope form is
-------(1)
Here

Substituting values in equation (1)

6x
x=10
So replace "x" in 6x with 10 and you get,
6(10)
It can be seen as
6 x 10
and 6 x 10 is 60.
So your answer would be 6x = 6(10) = 60
Answer:the library checks out 2 times more fiction books than the nonfiction books.
Step-by-step explanation:
Total number of fiction books that the Library checks out in an hour is 4.
Total number of non fiction books that the Library checks out in an hour is 2.
To determine how many times more fiction books that they check out than the nonfiction books, we would divide the total number of fiction books that the Library checks out in an hour by the total number of non fiction books that the Library checks out in an hour. It becomes
4/2 = 2
