Answer:
The central angle measure of the sector in radians is .
Step-by-step explanation:
A sector of a circle is the portion of a circle enclosed by two radii and an arc. It resembles a "pizza" slice.
The area of a sector when the central angle is in radians is given by
where
r = radius
θ = central angle in radians
We know that the area of the sector is and the radius is 6 cm. Applying the above formula and solving for the central angle (
) we get that
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,
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.
Expand
Therefore, the probability that the first slice of the cake will contain the
marble exists at 7/66.
