If a(3,4) and b(10,4) are the end points of a diameter of circle "o", what is the area of the circle o (a) (65π)/2 (b) (53π)/2 (c) (53π)/4 (d) (65π)/4

Step-by-step explanation:

The formula of an area of a circle:

r - radius

We have the endpoints of a diameter of a circle.

The formula of a distance between two points:

Substitute the coordinates of the given points A(3, 4) and B(10, 4):

Therefore we have the length of the diameter: d = 7

We know: d = 2r. Therefore

Substitute to the formula of an area:

There is no such answer in the answers to choose.

Apparently you have some error in the coordinates of the endpoints.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

mrb

the answer is 24
