The endpoints of a diameter of a circle are ​A(3​,​1) and ​B(8​,13​). Find the area of the circle in terms of pi.
Talja [164]

Answer:

A = 169π/4

Step-by-step explanation:

From these two given points we find the length of the diameter of this circle, using the Pythagorean Theorem:

d^2 = (8 - 3)^2 + (13 - 1)^2, or

d^2 = 25 + 144 = 169

Thus, the diameter, d, of this circle is √169, or 13.  

The radius is thus 13/2 units.

The area formula is A = πr^2.  Here the area is

A = π(169/4), or A = 169π/4

Factor the following:

x^2 + 3 x + 2

The factors of 2 that sum to 3 are 2 and 1. So, x^2 + 3 x + 2 = (x + 2) (x + 1):

Answer: (x + 2) (x + 1)
