I'm learning the exact same thing so give me some question and I can see what I can do!
Answer: d = 42/r - 6m/r
Step-by-step explanation: Isolate the variable by dividing each side by factors that don't contain the variable.
The answer is 72 all u need to do plug in the numbers where the letters are
For this case what you should know is that by definition the volume of the cone is given by:
V = ((pi) * (r ^ 2) * (h)) / (3)
Remembering that:
r = d / 2
Substituting the values:
V = ((pi) * ((d / 2) ^ 2) * (h)) / (3)
V = ((pi) * (((10) / 2) ^ 2) * (12)) / (3)
V = 314.16 ft ^ 3
Answer:
V = 314.16 ft ^ 3
The nearest option is:
300 cu. ft
