<span>Together with triangles, circles comprise most of the GMAT Geometry problems.
A circle is the set of all points on a plane at the same distance from a single point ("the center").
The boundary line of a circle is called the circumference.</span>
We can find the radius by using the formula: C = 2(pi)(r)
We'll use 3.14 for pi.
And solve for r.
18.84 = 2(3.14)r ; Start
18.84 = 6.28r ; Multiply 3.14 by 2
3 = r ; Divide both sides by the coefficient of r. Which is 6.28
So, the radius is 3 miles.
Answer:
(5, 15)
Step-by-step explanation:
-x + 6x = 5
5x = 5
x = 5
y = 3 (5)
y = 15
You can substitute 6x for 2y because it says y = 3x. So 2y is gonna be 6x because you have to multiply it by 2 since it's 2y not just y.
