Answer:

The answer is 972

Step-by-step explanation:

The equation of a sphere for volume is $V=\frac{4}{3} \pi r^{3}$ so, you insert the 9 as the radius for the r. so the equation would then be $V=\frac{4}{3} \pi 9^{3}$ then you solve it.

First you do $9^{3}$ = 729

Second take the equation and do order of operations $V=\frac{4}{3} \pi 729$

Next, do $\frac{4}{3} 729$ =972

If BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6, what are the values of x and AC?

Keith_Richards [23]

Answer: x=7 and AC = 44 unuts.

Step-by-step explanation:

We know that the diagonals of a parallelogram bisect each other. (i)

Here in parallelogram ABCD , AC and Bd are diagonals intersecting at E.

BE = 2x + 2, BD = 5x – 3, and AE = 4x – 6

Using (i)

$BE=\dfrac{BD}{2}\\\\2x+2=\dfrac{5x-3}{2}\\\\ 2(2x+2)=5x-3\\\\ 4x+4= 5x-3\\\\ 5x-4x=4+3\\\\ x= 7$

Now , AE = 4(7)-6 = 28-6 = 22

AC =2 AE = 2 (22) =44 units.

Hence, x=7 and AC = 44 unuts.
