Hey there !
7C5 = 7 x 6 x 5 x4x3/5 x 4 x 3 x2x1 = 7
Hence option d is correct z
For the fifth term, n = 5.
Just replace n with 5 in the expression.
Then evaluate the expression.

Step-by-step explanation:
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.
