Answer:
x= 105/4
x=4
Step-by-step explanation:
The formula for the volume of a sphere is V = (4/3) * π * r³. Knowing this, we can plug in the radius:

The sphere's volume is approximately 2144.66 mm^3.
Answer:
k > 7
Step-by-step explanation:
Given the inequality statement: 4k - (5 + 3k) > 2
Distribute -1 into (5 + 3k):
4k -5 - 3k > 2
Next, add like terms:
k - 5 > 2
Add 5 to both sides of the inequality:
k - 5 + 5 > 2 + 5
k > 7
