a circle is centered at the point (-7, -1) and passes through the point (8, 7).the radius of the circle units. the point (- ) lies on this circle.
( fill in the blanks)

Part 1) The radius of the circle is r=17 units

Part 2) The points (-15,14) and (-15,-16) lies on this circle

Step-by-step explanation:

step 1

Find the radius of the circle

we know that

The distance between the center of the circle and any point on the circle is equal to the radius of the circle

the formula to calculate the distance between two points is equal to

we have

(-7, -1) and (8, 7)

substitute

step 2

Find out the y-coordinate of point (-15,y)

The equation of the circle in standard form is equal to

where

(h,k) is the center

r is the radius

substitute the values

Substitute the value of x=-15 in the equation

square root both sides

therefore

we have two solutions

point (-15,14) and point (-15,-16)

see the attached figure to better understand the problem

it would be a on edgenuit y

the diagram below is your final answer

cool? what is the actuall ?
