Answer:
Step-by-step explanation:
The trick is to find the radius. The surface area does that.
A =4* pi * r^2
20096 = 4 * 3.14 * r^2
20096 / 4 = 3.14 * r^2
5024 = 3.14 * r^2
5024 / 3.14 = r^2
r^2 = 1600
√r^2 = √1600
r = 40
Now all you do is use r to find the Volume
V = (4/3) * 3.14 r^3
V = (4/3) * 3.14 * 40^3
V = 1.333 * 3.14 * 64000
V = 26796.67
Answer: 448
Step-by-step explanation:
Answer: 16
Step-by-step explanation:

in order to get rid of the negative sign and the 2 to isolate t, we must multiply both sides by -2

The answer is in the enclosed diagram
Answer:
y = x - 1
Step-by-step explanation:
Find the slope:
(-4 - (-2))/(-3 - (-1))
-2/-2 = 1
y = x + b
Plug in one of the points:
(-1,-2)
-2 = -1 + b
b = -1
y = x - 1
