Question

find diameter of a circle whose center is (4,0) passes through point (7,-4)​

Answer 1

ANSWER:-

DISTANCE BETWEEN TWO POINTS IS 10 UNIT.

SOLUTION:-

◆ A (X,Y) ,

◆ B (7,-4) , and

◆ C (4,0)

◆ BY SECTION FORMULA:-

● C(4)=A(X) + B(7)/2

● 8=X+7

● X= 1

● C(0)=A(Y) + B(-4)/2

● 0=Y - 4

● Y=4

◆ BY DISTANCE FORMULA:-

● AB = √(7-1)^2 + (4+4)^2

● AB = √36+64

● AB = √100

● AB = 10 UNIT
