Answer:
48
Step-by-step explanation:
u • w
= (i + 6j ) • (9i - 2j )
= (1 × 9 ) + (6 × - 2 )
= 9 + (- 12)
= 9 - 12
= - 3
v • w
= (5i - 3j ) • (9i - 2j )
= (5 × 9) + (- 3 × - 2)
= 45 + 6
= 51
Then
u • w + v • w
= - 3 + 51
= 48

Answer: option A
Step-by-step explanation:
The volume of a cylinder can be calculated with the formula:

Where r is the radius and h is the height of the cylinder.
The radius is diameter divided by 2, then:

Substitute the radius into the formula. Then you get the following equation that can be used to find V, the volume of the cylinder:
