area of a circle is pi x r^2

r = 9 ft so 9^2 = 81

so the full area in terms of PI is 81PI

 now the shaded area is 120 degrees ( one third of the full area)

120/360 = 1/3


 so divide 81 by 3 = 81/3 = 27

so shaded area is 27PI

Total area: pi*9^2 = 81pi

Shaded area = Total area / 3, because 120/360 = 1/3

So Shaded area = 81pi/3 = 27pi

Rudik [331]

Answer:

<u>i think</u> it is 40%

Step-by-step explanation:

she made 2/5 shots so

2/5*2=4/10

i times it by 2 because its out of 100

Identify the number of solutions. Y&lt; -1/3x+5, y&gt; -1/3x-1.
Elenna [48]

Answer: C. No solution. ( top shaded. Middle not. Bottom shaded.


Step-by-step explanation:

Given inequalities

y< -1/3x+5 and

y> -1/3x-1.

If we draw graph for y< -1/3x+5 equation, it would be a dotted line and we would shade down the dotted line because we have less than < symbol there.

Now, if we draw graph for second inequality y> -1/3x-1, it would also be a dotted line and we would shade up of dotted line because we have greater  than > symbol there.

Now, we can see that slopes of both dotted lines are same that is -1/3.

So, there would not be any common shaded region.

Therefore, there would not by any solution of the system of inequalities.

And correct option is C option.

C. No solution. ( top shaded. Middle not. Bottom shaded.
