56.52 in^3

V(cylinder) = pi * r^2 * h
V = pi * 3^2 ^ 6
V = pi * 9 * 6
V = 54pi

V(sphere) = (4/3) * pi * r^3
V = (4/3) * pi * 3^3
V = (4/3) * pi * 27
V = 36pi

54pi - 36pi = 18 pi
18 * 3.14 = 56.52

If a cot α = 1 and b cos α = 1, find a2 – b 2

S_A_V [24]

The equivalent expression of the different of two square is -1

Given the following expressions

a cot α = 1

a = 1/cot α = sinα/cosα

b = 1/cos α

We are to find the expression a² - b²

According to difference of two squares;

a² - b² = (a + b) (a - b)

Substitute the given expressions into the formula as shown:

$a^2 - b^2 = (\frac{sin \alpha}{cos \alpha} )^2 - (\frac{1}{cos \alpha} )^2\\a^2 - b^2=\frac{sin^2 \alpha}{cos^2 \alpha} -\frac{1}{cos ^2 \alpha}\\a^2 - b^2=\frac{sin^2 \alpha-1}{cos^2\alpha}\\a^2 - b^2=\frac{-(1-sin^2\alpha)}{cos^2\alpha} \\a^2 - b^2=\frac{-os^2 \alpha}{cos^2 \alpha}\\a^2 - b^2 = -1$

This shows that the equivalent expression of the difference of two squares is -1

Match the events described to the likelihood of their occurrence.

Ksju [112]

Answer:

Step-by-step explanation:

1. likelihood that edna picks a cherry.....impossible...because there is no cherries in the bag

2. communication....likelihood of an n is 2 / 13...15% chance...well...out of the answer choices, I am going with unlikely

3. mississippi....likelihood of s or p : 4/11 * 2/11 = 8/11...73% chance....its not certain...so I am going with neither likely or unlikely

4. all girls school....picking a girl is certain
