Determine whether the statement is true or false. If it is true, explain why. If it is false, explain why or give an example tha
frosja888 [35]

Answer:

False

Step-by-step explanation:

the <u>dot product</u> between two vectors A and B is:

A·B=ABcos\theta

where \theta is the angle between the vectors, if they are parallel, this angle is zero. so  \theta=0

and so the dot product is:

A·B =ABcos(0)

and since  cos (0)=1

the dot product is equal to

A·B=AB

The dot product of parallel vectors is NOT zero

I need to find surface area of a cylinder. Formula being used: S.A= L x W +
Arturiano [62]

Answer:

90π yd²

Step-by-step explanation:

the surface area of a cylinder is the sum of the lateral area and twice the aera of one end of the cylinder:  π·d·l, where l represents the length of the cylinder.  Here, the lateral surface area is π·6 yd·12 yd, or 72π yd².

The two ends add the following to the total surface area:

2·π·(d/2)², or 2π·d²/4.

Thus, the total surface area of the cyl. is

A = 2π·(6 yd)²/4 + 72π yd², or

A = 18π yd² + 72π yd² = 90π yd²

Note:  Please check your source.  L x W +  2pi ·r ^2 is incorrect.
