Answer: c
explanation: (3^-2)^4 equals 1.5x10^-4
find which choice equals the same as the given equation.
Answer:
The radius is 5 units
(-7,-1) and (-7,5) lies on the circle
Step-by-step explanation:
Use the distance formula to find the distance between the center and the given point that gives you the radius.

The center is (-3,2) and the point on the circumference is (1,5)





The radius is 5 units.
The equation of the circle is given by:
When x=-7, we obtain y by substituting into the equation of the circle:
or y=5
Therefore (-7,-1) and (-7,5) lies on the circle.
2)
2*120 + 2*3.14*40 = 240 + 251.2 = 491.2;
