The diameter of a circle has endpoints of (2, 5) and (-4, 13). What is the correct equation of this circle? Pls explain and I wi

Bezzdna [24]

Answer:

Option 4

Step-by-step explanation:

Midpoint of the diameter is the center.

Use midpoint formula to determine the coordinates:

x = (2 - 4)/2 = -1
y = (5 + 13)/2 = 9

Find the radius using the midpoint and one of the endpoints and the distance formula:

r = $\sqrt{(-1 - 2)^2 + (9 - 5)^2} = \sqrt{9+16} = \sqrt{25} = 5$

Use the equation of the circle:

(x - (-1))² + (y - 9)² = 5²
(x + 1)² + (y - 9)² = 25

Correct choice is 4

Answer:

15.28

Step-by-step explanation:

first we divide 96 by 3.14 to get the diameter

96÷3.14=30.57

now we have the diameter we divide by two to get the radius

30.57÷2=15.28

15.28 is your radius
