Answer:
9) five hundred and forty three thousand, six hundred and ninety-eight
500,000 + 40,00+ 3,000+ 600+ 90+ 8 = 543,698
10)forty-five million nine hundred eighty-seven thousand one hundred fifty-nine and nine tenths
40,000,000 + 5,000,000 + 900,000 + 80,000 + 7,000 + 100 + 50 + 9 + 0.9 = 45,987,159.9
Alright, let get started.
49 could be written as 
, it means
could be written as i
As we know, 
That is the answer:
Hope it will help :)
r = d/2
r = 15.6/2
r = 7.8 in.
thus the radius of the right circular cone is 7.8
v = 1/3(3.14)(7.8)^2(12.4)
v= 1/3(3.14)(60.84)(12.4)
v= 2368.866/3
v = 789.622
thus the volume of the right come is 789.622 cubic inches
