Artyom0805 [142]4 years ago
7 0

Answer:

8

Step-by-step explanation:

To write the equation of a circle, use the formula (x-h)^2+(y-k)^2 = r^2 where the center of the circle is (h, k).

This means the equation is x^2 + y^2 = 64 has r^2 = 64. This means the radius is √64 = 8.

77julia77 [94]

Answer:

20 square units

Step-by-step explanation:

If Polygon C has an area of 40 square units, and we are told that Polygon D is a copy of Polygon C but with a scale factor of 1/2, then everything for Polygon D would just be one-half of what it was for Polygon C. Thus, the area would be half of 40 square units, or, 20 square units.
