"a grain silo is shown below.
what is the volume of grain that could completely fill this silo rounded to the nearest whole number? use 22/7 for pi.
a) 19,008 ft3
b) 19,461 ft3
c) 6,336 ft3
d) 453 ft3"

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6
