I know this one give me like 5 minutes
9u means you're multiplying 9 into that vector, both components. Same with the 2v. 9*3 = 27 and 9*-1 = -9, so your new vector u is <27, -9>. Now let's do v. 2* -6 (twice) = -12, so your new v vector is <-12, -12>. Add those together now, first components of each and second components of each. 27 + (-12) = 15; -9+(-12)=-21. So the addition of those gives us a final vector with a displacement of <15, -21>
For this case we have that by definition, the volume of a cuboid is given by:
Where:
L: It's the long
A: It is the width
h: It is the height
According to the problem data we have:
So, the volume of the cuboid is:
Finally, the volume of the cuboid is: 
Answer:
Answer:
h = A/πr²
Step-by-step explanation:
Surface area (A) of a cylinder = πr² × height (h) , where r is the radius.
h = A ÷ πr² = A/πr²
