Answer:
r = 18 cm
Step-by-step explanation:
Hello
The formula for circumference is 2*Pi*r
So you have the valur for that formula:
2*Pi*r = 36Pi
r = 36/2
r = 18 cm

The midpoint joining points (-1,-1) and (-5,10) is (-3, 4.5)
<h3>What is Midpoint?</h3>
midpoint is the point that represents the center or middle. in geometry, it is the center of the figure in question.
<u>Given data</u>
points (-1,-1) and (-5,10).
<h3>solving for the midpoint</h3>
let be given point be equivalent to
(x1, y1) = (-1, -1)
(x2, y2) = (-5, 10)
let the midpoint be (X, Y)
for X
X = (x1 + x2)/2
X = (-1 + -5)/2
X = -6/2
X = -3
for Y
Y = (-1 + 10) / 2
Y = 9/2
Y= 4.5
hence the midpoint is (-3, 4.5)
