Answer:
Radius of the cone's base is 3x ....
Step-by-step explanation:
We have given that the volume of a cone is 3πx³
Height = x units.
The volume of a cone of radius r and height h units is given by:
V= 1/3 π r² *h
Simply plug the values given in the question into the above mentioned equation:
1/3πr²*x = 3*π*x³
1/3r²*x= 3x³
r² = 3*3*x³/x
r²=9x²
Taking square root at both sides we get:
√r² =√9x²
r = 3x
Thus the radius of the cone's base is 3x.
Answer:
is numper
Step-by-step explanation:
Since the spinner is labelled A, B, C, D, there are four possible landing for the spinner.
Thus, the sample space is {A, B, C,D}.
Therefore, the number of <span>elements in the sample space for spinning a spinner labeled A, B, C, D</span> is 4.
Answer:
280,280
Step-by-step explanation:
i believe you just multiply 45.5 times 5280
Let's solve your equation step-by-step:
x^2+6x-16=0
Factor the left side of the equation:(x-2)(x+8)=0
Set factors equal to 0: x-2=0 or x+8=0, x=2 or x=-8
Your answer is x=2 or x=-8, doesn't matter which, both are correct.
Hope this helps!:)
