Answer:
18/2 : 9
Step-by-step explanation:
From the identity,
sin^2(x)+cos^2(x)=1
then
cos(x)=sqrt(1-sin^2(x))
where sin(x) is given as 0.42.
Note that the above answer applies to 0<x<90 degrees

Answer:
23 feet
Step-by-step explanation:
Givens
Volume = pi r^2 h
r = 11
V = 2783 pi
Solution
2783 pi = pi 11^2 * h Cancel the 2 pi's
2783 = 11^2 h Expand 11^2
2783 = 121 * h Divide by 121
2783/121 = h
h = 23 feet
