Answer:
The first one would be 9
The second one would be 4
Step-by-step explanation:
By adding the same numbers, you make the equations equal and therefore true.
No need for pie here!
8x4=32
(3x3)/2=4.5
(3x2)/2=3
32+4.5+3= 39.5
.5-.625, C=.5625 therefore C would be the answer. I found this by taking all of the fractions and dividing the numerator by the denominator and then lining up all of the decimals till one worked out.

²⁰¹²C₂₀₁₁ = (2012)! / [(2011)! (2012-2011)!]
²⁰¹²C₂₀₁₁ = (2012)! / [(2011)! (1)!]
Simplify 2012! / (2011)! = 2012
²⁰¹²C₂₀₁₁ = (2012)! / (1)! = 2012
Answer: 889.66
Step-by-step explanation:
Volume of sphere is 4/3 \pi r3 and cylinder is \pi r2 h,
r=5
h=8
volume of sphere is 4/3 x 3.14 x 5x5x5 / 2 (since half of sphere) = 261.66
volume of cylinder is 3.14 x 5x5 x 8 = 628
total volume = 261.66+628 = 889.66
