Step-by-step explanation:
The question is to simplify 
<em>We combine like terms, as in, combine cubes with cubes, squares with squares, numbers with numbers and so on.</em>
- There are 2 cubed terms, so they should be combined.
- There are 2 numbers, so they should be combined.
- Others, leave as is.
So we have:

This is the simplified form of the sum given.

(Hopefully you can comprehend what I just explained lol-)
16 as 1-4 =4secs so 1-16=16
Formula for area of a circle: A= C^2/ 4 π
A= 64^2/ 4 π
A= 4,096/ 4 π
A=3,216.99087728
A≈3,216
The area of the clock is about 3,216 inches
