Question

Answer the following prompts with numerical answers only. If necessary, round answers to the nearest tenth of a unit. The diameter of circle P has endpoints A (-1,5) and B (4, -3). Use the midpoint formula to find the coordinates of the center of the circle, P (X,Y). P(_,_). Use the distance formula to find the length of the radius of circle P. The length of the radius of circle P is -- units. Using 3.14 to approximate TT, the circumference of circle P. The circumference of circle P is approximately ---- units. Using 3.14 to approximate TT, the area of circle P is approximately --- square units.

Answer 1

Answer:

The answer is below!!

Step-by-step explanation:

To find the midpoint, add the 2 x values and divide by 2 and then do the same with the y values:

Midpoint = (-1 +4)/2 , (5 + -3)/2

Midpoint = 3/2, 2/2

Center of circle = (3/2, 1)

Radius = √((3/2 - -1)^2 + (1-5)^2)

= √89/2 = 4.7 units.

Circumference = 2 x PI x r

= 2 x 3.14 x 4.7 = 29.5 units

Area = PI x r^2

= 3.14 x 4.7^2

= 3.14 x 22.09

= 69.4 square units.
