$15.41
Multiply the $1.79 by 4 which gets you $7.16. Then, add the $7.16 to the $8.25 and that gets you $15.41.
Answer:

Step-by-step explanation:
The formula of a volume of a sphere:

R - radius
We have R = 3 ?. Substitute

If the radius is 30, then the volume is:

If 30 is the length of diameter, then the radius R = 30 : 2 = 15.
Therefore the volume:

Answer:
x=9
Step-by-step explanation:
5( x + 7) - 3 ( x - 4) = 7x + 2
Distribute
5x+35 - 3x +12 = 7x +2
2x +47 = 7x+2
Subtract 2x from each side
2x+47-2x =7x -2x+2
47 = 5x+2
Subtract 2 from each side
47-2= 5x+2-2
45= 5x
Divide by 5
45/5 =5x/5
9 =x
