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.

Do you mean how many different words can be made from using only 3 letters from the word "question"? Are they supposed to be the same 3 letters?
ton, son, not, sue, sit
Answer:
72 ?
Step-by-step explanation:
Answer:
p = all real numbers
Step-by-step explanation:
First distribute the numbers to the expressions inside the parenthesis
-11 + 10(p + 1) = -16 + 5(2p + 3)
-11 + 10p + 10 = -16 + 10p + 15
Then, add up the like terms
10p - 1 = 10p - 1
Add one to both sides
10p - 1 = 10p - 1
+ 1 + 1
10p = 10p
Divide both sides by 10
10p/10 = 10p/10
p = p
This means that no matter what you plug in for p, it will always be true.
