The area of the shaded region is 
Step-by-step explanation:
<u><em>The correct question is</em></u>
A circle with radius of 4cm sits inside a circle with a radius of 11cm. What is the area of the shaded region?
The shaded region is the area outside the smaller circle and inside the larger circle
we know that
To find out the shaded region subtract the area of the smaller circle from the area of the larger circle
so
simplify
where
r_a is the radius of the larger circle
r_b is the radius of the smaller circle
we have
substitute

Answer:
$2,000 or 6.25%
Step-by-step explanation:
1000 x 2 = 2000
28000 + 2000 = 30000 Juan's salary after 2 years
500 x 2 = 1000
31000 + 1000 = 32000 Mariana's salary after 2 years
30000 - 32000 = 2000 difference in salary
2000/32000 x 100= 6.25 difference in salary in percentage
The probability is 7/20.
There are 20 outcomes in the sample space:
2(1) 2(3) 2(5) 2(7) 2(9)
3(1) 3(3) 3(5) 3(7) 3(9)
4(1) 4(3) 4(5) 4(7) 4(9)
5(1) 5(3) 5(5) 5(7) 5(9)
Out of these, 14 are two digit products. Out of those 14, only 7 are odd. Thus the probability is 7/20.
