Answer :
We have: center(2,1) and a point on the circle (2,5):
r=5-1=4
circumference of a circle: [tex]2*\pi*r=2*3,14*4=25,12[/tex]
Answer 3: 25
r=5-1=4
circumference of a circle: [tex]2*\pi*r=2*3,14*4=25,12[/tex]
Answer 3: 25
The approximate circumference of the circle is 25 units.
What is a circle?
A circle is a geometric figure that has a center. Al the points on the circumference of the circle from the center is same.
The circle has a center at (2, 1) and the passes through the point (2, 5).
Therefore, the radius of the circle is r = (5 -1) units = 4 units.
The circumference = 2 × π × r units = 2 × π × 4 units ≈ 25 units.
