Answer:
2258 cu. units
Step-by-step explanation:
you take 22/7 multiply by radius squared and multiply that by 5
If u and v are indeed vectors,

,
PEMDAS is important
Parentheses
Exponents
Multiplication
Division
Adding
Subtracting
There's no parentheses or exponents, so the first is multiplication. 9*3 is 27. Next is division, 6/2 is 3. Next is adding.
15+3+27=45
Answer:
2b. 3(2-x)
2c. add the 5x-10
5(x-2)
3.its suppose to be 12x+3=3(4x+1)
3(4x+1)=12x+3
