Answer:

Using circumference of the circle

Step-by-step explanation:

If diameter of circle is not given and we know the value of its circumference, radius of the circle can be obtained.

$C = 2\pi \: r \\ \\ \therefore \: r = \frac{C}{2\pi} \\$

Find the midpoint of A and B where A has coordinates (2,7) and B has coordinates (6,3).

Veronika [31]

Given that the coordinates of the point A is (2,7) and the coordinates of the point B is (6,3)

We need to determine the midpoint of A and B

Midpoint of A and B:

The midpoint of A and B can be determined using the formula,

$Midpoint =(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2})$

Substituting the points (2,7) and (6,3) in the above formula, we get;

$Midpoint =(\frac{2+6}{2}, \frac{7+3}{2})$

Adding the numerator, we have;

$Midpoint =(\frac{8}{2}, \frac{10}{2})$

Dividing the terms, we get;

$Midpoint =(4, 5)$

Thus, the midpoint of the points A and B is (4,5)
