Answer:

a. 72

Step-by-step explanation:

Factorial (!) means take that number and multiply by all the numbers below it to 1

9! = 9*8*7*6*5*4*3*2*1

(9-2)! = 7! = 7*6*5*4*3*2*1

9*8*7*6*5*4*3*2*1

------------------------------

7*6*5*4*3*2*1

Canceling common factors

9*8

May I please have help from anyone thank you so much !

You’re solving for the volume of the cylinder. so the way you would do this is the area of the base of the cylinder (pi times radius squared) which in this case would be 3.14 x 10^2 which is 314. you would then multiply by h, the height, which here is 10. 314 x 10 is 3140.
