Circumference=Diameter*pi
56.5=3.14*D
Divide both sides by 3.14
D=17.99
Diameter= 2(radius)
17.99= 2r
Divide both sides by 2
The radius is about 8.995 or 9m
Answer:
Step-by-step explanation:
This is called a 'System of equations'.
Say that you have these two expressions, and the unknown is "b".
5b = y
4b+2 = y
Now we can solve two ways; graph it or solve it.
Solving it, we can see that they both equal y, so:
5b=4b+2
move 4b to the left side by subtraction:
(5b-4b) =2
b = 2
let's see what y equals when b = 2
5 * 2 = y
10 = y
Graphing it we see they intersect, or solve at
(2,10) or b=2, y=10
Hope this helps!
You need to show us the numbers to solve the area. but if you cant that's ok. remember to find the area for a rectangle you do length time width ( I'm guessing is a rectangle cause its usually a rectangle lol )
D is the right answer bc I am smart
