The area of the shaded region is 40π/3 square cm if the radius of the small circle r is 3 cm and the radius of the large circle R is 7 cm.
<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have a circle in which the shaded region is shown.
The radius of the small circle r = 3 cm
The radius of the large circle R = 3+4 = 7 cm
The area of the shaded region:
= area of the large circle sector - an area of the small circle sector
= (120/360)[π7²] - (120/360)[π3²]
= 49π/3 - 3π
= 40π/3 square cm or
= 13.34π square cm
Thus, the area of the shaded region is 40π/3 square cm if the radius of the small circle r is 3 cm and the radius of the large circle R is 7 cm.

Between 8 and 9
is the correct answer (8.06)
The <u>correct answer</u> is:
<span>Relative frequencies are the probabilities occurring in sampling distributions.
Explanation:
Relative frequencies are the fraction of times an event occurs within a sample.
This is the same definition as experimental probability; thus relative frequencies are the probabilities occurring in sampling distributions.</span>
the answer is the first one
