The equation to find volume is V=

r²h and you know all of your numbers other than h so you plug all that in. 100=3.14×2²×h → 100=3.14×4×h → 100=12.56×h → Divide 12.56 from both sides 100÷12.56=12.56×h÷12.56 → 7.96cm=h.
I hope that helps!
Answer: 12.6 m
Step-by-step explanation:
Use the pythagorean theorem, we get that the height, or x, is
sqrt(22x22-18x18) = sqrt(484-324) = sqrt(160) = 4sqrt(10) = 12.6 m
20/42 + 14/42 - 8/42 = 26/42
The value of the expression is 48.424
Answer:
Perpendicular
Step-by-step explanation:
Here, the slopes of the lines are 1 & -1
( they are same with opposite symbols) so, the lines are perpendicular
