= 2009.6
The "mean" is the "average" you're used to, where you add up all the numbers and then divide by the number of numbers.
Answer:
Step-by-step explanation:
if (x,y) is any point on unit circle then
x²+y²=1²
x²+y²=1
(3/4)²+y²=1
9/16+y²=1
y²=1-9/16=(16-9)/16=7/16
y=±√7/16
Volume of prism = 3 1/2 x 3 1/2 x 7 = 85 3/4 cubic inches
90 - 85 3/4 = 4 1/4 ( 4.25) cubic inches difference
