Answer:

Step-by-step explanation:
The formula of a surface area of a sphere:

R - radius
We have

Substitute and solve for R:
<em>divide both sides by π</em>
<em>divide both sides by 4</em>

The formula of a volume of a sphere:

Substitute:

Answer:
1032 yds
Step-by-step explanation:
Al =(a+b+c)h
Answer:
C) (3 , 2)
Step-by-step explanation:
y is greater than 2x - 7.
Note the point values (x , y). y, in this case, must be greater than x after it is simplified.
~
(3 , -2)
Plug in 3 for x, and -2 for y:
(-2) > 2(3) - 7
-2 > 6 - 7
-2 > -1
(False).
~
(4 , 1)
Plug in 4 for x, and 1 for y:
(1) > 2(4) - 7
1 > 8 - 7
1 > 1
(False).
~
(3 , 2)
Plug in 3 for x, and 2 for y:
(2) > 2(3) - 7
(2) > 6 - 7
2 > 1
(True).
~
∴ C) (3 , 2) is your answer.

Answer:
Domain is A
Range is D
Step-by-step explanation:
it's all x because the line will go up and down on both directions infinitely hitting every x coordinate. The range is all y because it will also extend infinitely upwards and downwards. This is not a parabola so there i no limitation
Answer:
b. 22.2
Step-by-step explanation:
I put it as an equation.
3.2w=72
Then solved for w
3.2w/3.2=72/3.2
Simplify
22.5
