Answer:
169π or 530.93
Step-by-step explanation:
The formula for the area of a circle is πr²
Here, the radius is given to be 13.
So, let's just plug it into the formula as r
π x 13²
π x 169
169π
The radius is 169π. If you want to multiply out the π you would get 530.93, which is equivalent of course.
Answer:
c
Step-by-step explanation:
when a decimal is in front of a number, its converted to a percent
D) 40% 2/5=40 so 40 percent chance
Anything less than 12 (must be positive numbers and it mustn’t be 0) is greater than 0.
2x + y = -8 (-4, 0)
2(-4) + 0 = -8
-8 + 0 = -8
-8 = -8
x - y = -4 (-4, 0)
-4 - 0 = -4
-4 = -4
the ordered pair (-4, 0) is a solution to the system because it makes both equations true.
