The slope in short is:
4/7
The radius is 4.
Find the radius of the circle whose equation is (x + 5)2 + (y + 8)2 = 16
Answer:
Find the Diameter!
To find the diameter, get the cirumference, divide it by 2, and multiply it by Pi (3.14)
For this certain equation, it appears the circumference is 13. 13/2 is 6.5. 6.5 times 3.14 is 20.41.
