The probability that the first slice of the cake will have the marble exists

7/66.

<h3>How to determine the probability using parts A and B?</h3>

Part A of the question demands that the volume of the cake be

estimated.

The volume of the cake exists, $V=\pi(\frac{d}{2} )^{2} h \\

$&V=\pi(\frac{9}{2} )^{2} * 4

$V=81 \pi

The part B of the question requires that the volume of each cut be

computed

The volume of each cut exists, V = 27

To estimate the required probability

We simply divide the volume of each cut by the volume of the cake.

$P=\frac{27}{81 \pi}

$P=\frac{1}{3 \pi}

Expand $\pi$

$&P=\frac{7}{3 * 22} \\

$&P=\frac{7}{66}

Therefore, the probability that the first slice of the cake will contain the

marble exists at 7/66.

lidiya [134]

Answer:

It will cost: £28.28

Step-by-step explanation:

Area of sphere = 4 x π x r2

Area of Circle = 4 x π x 3^2 = 113.097 (radius is half of diameter)

113.097 / 0.25 = 28.28

Use the diagram below to find the value of each variable.
s2008m [1.1K]
Z=95° as opposite angles are equal
The angle next to 120° is 60° as angles on a straight line sum to 180°
This means that y=25° because angles in a triangle sum to 180°
Therefore x=155° as angles on a straight line sum to 180°
