Answer:

Step-by-step explanation:
The standard form of an equation of a circle:

(h, k) - center
r - radius
We have the endpoints of the diameter of a circle (-8, -6) and (-4, -14).
The midpoint of a diameter is a center of a circle.
The formula of a midpoint:

Substitute:

We have h = -6 and k = -10.
The radius is the distance between a center and the point on a circumference of a circle.
The formula of a distance between two points:

Substitute (-6, -10) and (-8, -6):

Finally we have

Answer:
A) r=2t
B) 4
t²
C) 4
(30)² which will end up being 11310 in²
Step-by-step explanation:
A) If it increases 2 inches every minute, you would take that and put it with the t, aka time.
B) A=
r² which will translate into A=
(2)²
C) You take the half-hour, which is 30 minutes, and translate that into t then place that into your calculator and get an answer of 11,309.73 and then round up to the whole number
