Answer:
Step-by-step explanation:
v=4pi*r^3/3=3052.08
4*3.14/3*r^3=3052.08
4.2*r^3=3052.08
r^3=3052.08/4.2=726.7
so r ≈9

Answer:
5.5
Step-by-step explanation:
Given:
18 -7x = -20.5
We can find x by subtracting 18, then dividing by the coefficient of x. (This is known as a 2-step equation.)
-7x = -38.5 . . . . . subtract 18 from both sides
x = -38.5/-7 = 5.5 . . . . .divide by -7
The value of x is 5.5.
