Answer:
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
