Answer:
r = 5 feet
Step-by-step explanation:
see attached for reference
recall that volume of a circular cone is given by
V = (1/3) πr²h, where
V = volume = given as 50π ft³
r = radius (we are asked to find this)
h = height of cone = given as 6 feet
Substituting the above known values into the equation:
V = (1/3) πr²h
50π = (1/3) π (r²)(6)
50π = π (r²)(2) (divide both sides by 2)
25π = π r² (divide both sides by π)
25 = r²
r = ±√25
r = ±5 (since radius cannot be negative, we select the positive value
r = 5 feet
Answer:
The correct answer is B ; Karla must determine the area of a floor in her house.
Answer:
A= (3*X - 6
)/(X-4)
A=(3*2 - 6
)/(2-4)= -3+3
A=(3*4 - 6
)/(4-4) Unknown
Step-by-step explanation:
Answer:
22-9=16
so,
22-9
is 16
then you would take
16=16
so, you would have to divide the 2 numbers
then 1 is your answer
Step-by-step explanation:
Calculate circumference. You can do the math mentally with area & perimeter,but circumference is much more complex
