v = 4π r²h is to be solved for r.
Divide both sides of this equation by 4π*h:
v
--------- = r^2
4π*h
Next, take the positive square root of both sides:
v
r = √[----------- ]
4π*h
You may leave this result as is, or proceed further: Taking the + square root of 4 results in:
v
r = (1/2)√[----------- ]
π*h
Answer:

Step-by-step explanation:
Point-Slope form is: 
'm' - Slope
(x1, y1) - Point Coordinate
We are given the point of (-1,3) and the slope of 5.
Replace 'm' with 5, 'x1' with -1, and 'y1' with 3:

Answer: 7 7/8 hours long
Step-by-step explanation:
April worked 1 1/2 times as long as Carl did. 1 1/2 can be rewritten as 3/2. Number of Hours April worked on math project 3/2 times the Number of Hours Carl worked on Math project. Which Carl worked 5 1/4 hours long, which can be rewritten as 21/4
