Answer:
Solution given:
radius [r]= 9cm
volume of hemisphere =2/3 ×(πr³)=2/3×π×9³
=486πcm³ is your answer
Step-by-step explanation:
You need to solve for x.
You can do that by either setting both of the equations equal to each other. or Solve each one separately and subtract the EG equation from the EW to get GW
Answer:
x > 1
Step-by-step explanation:
Subtract 3 from both sides
8x + 3 - 3 > x + 10 - 3
Simplify
8x > x + 7
Subtract x from both sides
8x - x > x + 7 - x
Simplify
7x - 7
Divide both sides by 7
7x/7 > 7/7
Simplify
x > 1
