(Pts: 1) Please help me! Question is in attachment!

- - Solve:

To find the volume of a sphere:
 \frac{4}{3} *3.14*R^3

3.14≈π

Now since its telling us to use π, then we do our formula by multiplying by π.

π=3.14 (Approximate amount)

So:

4/3*3.14*9^3=3052.08

So you are correct.

When Radius=9, you plug in for R. :)

Can you answer this problem ​
geniusboy [140]

Answer:

The answer is D 7 degrees F

Explanation - 7°F

39 + (-5) + 7 = 39 - 5 + 7 = 41

then, the low was 39 + (-5) = 34

thus, 41 - 34 = 7

so, 7°F above the low of 34°F

Hope this helps :D

Solve and show your work please!x+7=2(3x-4)
Brrunno [24]

x + 7 = 2(3x - 4)         Remove the brackets

x + 7 = 2*3x - 4*2

x + 7 = 6x -  8            Subtract 7 from both sides.

x + 7 - 7 = 6x - 8 - 7  

x = 6x - 15                 Subtract 6x from both sides

x - 6x = - 15

-5x = - 15                   Divide by -5

-5x/-5 = -15/-5

x = 3
