Their is no simplest form for your question because your answer would be <u>
46</u> 100.
Hope I helped you : )
i can't really see the image but i'm sure it's pretty cool (:
Answer:
Given the expression: 
Let the value of the given expression in radians be 
then;

......[1]
We know the value of 
Substitute the given value in [1] we have;

Since, the value of
is 0, therefore, the value of
is in the form of:
; where n is the integer.
At n =0, 1 and 2, {Since, n is the integer}
Value of
and
therefore, the answer in radians either
or
V=4/3pi(r^3)
V=4/3pi(9^3)
V=3,054 inches^3
Think this is right
