Question

a diameter of a circle has endpoints p(-10 -2) and q(4 6).B.find the radius .If your answer is not an integer,express it in radical form.

Answer 1

find the length using these points

Answer 2

r^2=[(y1-y2)^2+(x1-x2)^2]

Answer 3

im a little bit confused

Answer 4

r=sqrt[(6-(-2))^2+(4-(-10))^2]
r=sqrt[8^2+14^2]

Answer 5

thats the answer

Answer 6

the square root of [8^2+14^2]=2sqrt65

Answer 7

r-sqrt[64+196]
r=sqrt(260)

Answer 8

thats the answer

Answer 9

260/4= 65
r=2sqrt(65)

Answer 10

yes or no is that the answer

Answer 11

the answer is r=2sqrt(65)
