I believe it would be A
Step-by-step explanation:
A deck of cards has 52 cards in it, so it cant be C or D, and with all the possibilities it could not be B
The surface area of this cylinder to the nearest thousandth is equal to 452.448 square feet.
<u>Given the following data:</u>
- Height of cylinder = 6 ft.
- Radius of cylinder = 6 ft.
To calculate the surface area of this cylinder to the nearest thousandth:
<h3>How to calculate surface area.</h3>
Mathematically, the surface area (SA) of a cylinder is given by this formula:

<u>Where:</u>
Substituting the given parameters into the formula, we have;

SA = 452.448 square feet.

Dot product is
a*b = |a|*|b|*cosα.
In our case
u*u =|u|*|u|*cos 0
u*u =|u|*|u|
12=|u|²
|u|=√12=√(4*3)=2√3
