You can just google volume of a sphere calculator and plug the radius (3 cm) in :)
X-(26 + 4) =65 the answer is x=95
Answer:
The solution is the result of 3x=0
and x−5=0 .x=0,5
Step-by-step explanation:

x=0
Set x−5
equal to 0 and solve for x
.
Tap for more steps...
x=5
The solution is the result of 3x=0
and x−5=0
.
x=0,5
Ok. I will put my explanation in the answer box because apparently it's not good enough in the comments.
2220 divided by 555 is 4.
We do this equation because we need to find out how many 555 miles go into 2220 miles. The answer is 4, which we need to convert to hours, so it is 4 hours.
1 hour is 555 miles
2 hours are 1110 miles.
3 hours are 1665 miles.
4 hours are 2220 miles which is what we need.
