For this case we have that by definition, the volume of a cube is given by:

Where:
l: It's the side of the cube
According to the statement we have:

Substituting we have:

Thus, the volume of the cube is 
ANswer:
The volume of the cube is 
False. because.....
the equation of a circle is (x-h)^2 + (y-k)^2 = r^2 and the center is (h,k)
if the center of a circle is (-5, -13) substitute the values into the equation
so....(x- -5)^2 + (y- -13)^2 = r^2 which is (x+5)^2 + (y+13)^2 = r^2
in this case, because you are only asking about the center of the circle from the equation the 81 or radius of the circle doesn't matter.
Answer:
168 units^3
Step-by-step explanation:
The volume of triangular prism is calculated like this : 1/2 × b×h×l (b: base, h: height, l: length)
1/2 × 7 × 6 × 8 = 168 units^3
Step-by-step explanation:
P(t) = 12,000 (2)^(-t/15)
9,000 = 12,000 (2)^(-t/15)
0.75 = 2^(-t/15)
ln(0.75) = ln(2^(-t/15))
ln(0.75) = (-t/15) ln(2)
-15 ln(0.75) / ln(2) = t
t = 6.23
