22. what is the exact volume of a cone whose base radius is 9 feet and whose height is 13 feet? show your work.

24. suppose you throw two fair number cubes. what is the probability that the sum of the results of the throw is 4,5, or 6? show your work and explain.

22- volume of cone = 1/3 πr^2h

= 1/3 ×3.141×9^2×13 =1102.7

question

24- total no of outcome when 2 dice thrown =36

set that sum is 4,5,6=

set of sum 4 - (1,3) , (2,2) ,(3,1)

set of sum 5 - (1,4), (2,3) ,(3,2), (4,1)

set of sum 6 - (1,5) ,(2,4) ,(3,3) ,(4,2) ,(5,1)

total set = 3+4+5=12

probability =12/36 = 1/3
