Answer:

3052.08

Step-by-step explanation:

We use the volume formula for spheres

$\frac{4}{3}$ πr³

Plug in 9cm for radius and evaluate

$\frac{4}{3}$ π(9)³

$\frac{4}{3}$ π*729

A line with a slope of 1/8 passes through the points (u, -9) and (6, -8). what is the value of u?

Pie

Answer:
u = -2

Explanation:
Slope of the line can be calculated using the following rule:
slope = (y2-y1) / (x2-x1)

We are given :
slope = 1/8
point (u,-9) represent (x1,y1)
point (6,-8) represent (x2,y2)

Substitute with the givens in the above equation and solve for u as follows:
slope = (y2-y1) / (x2-x1)
1/8 = (-8--9) / (6-u)
1/8 = (1) / (6-u)
1* (6-u) = 1*8
6-u = 8
u = 6-8
u = -2

Hope this helps :)

If / and / are midsegments of , what can you conclude about / and /? Verify your results by finding x when QR = 3x + 2 and NP =

Ad libitum [116K]

Midsegments are line segments that connect the midpoints of a triangle. If we have the condition that QR = NP, we have the equation
3x + 2 = 2x + 16
Solving for x
3x - 2x = 16 - 2
x = 14
Therefore, x is 14.
