Answer:
(x +4)^2 +(y +8)^2 = 64
Step-by-step explanation:
The equation of a circle with center (h, k) and radius r is ...
(x -h)^2 +(y -k)^2 = r^2
The circle centered at (h, k) = (-4, -8) with radius 8 has equation ...
(x +4)^2 +(y +8)^2 = 64
Answer:
212.5
Step-by-step explanation:
10=85
212.5=25
Hope that helped I use this when I'm doing math. It's called cymath it explain how they got the answer.
V = pi*r^2*h
V = 490
h = 10
490 = pi*r^2*10
r = 3.95
