Answer:

A_s=179  \ yd

Step-by-step explanation:

Area of Circle can be calculated using following formula

A=\pi r^{2}

Where r is radius of circle

<u>Area of outer circle (r=11 yd)</u>

A_1=\pi (11)^{2}\\A_1=379.94 \ yd

<u>Area of inner circle (r=8 yd)</u>

A_2=\pi (8)^{2}\\A_2=200.96 \ yd

Area of shaded region

A_s=A_1-A_2

A_s=379.94-200.96\\A_s=179  \ yd

Problem Solving with Angles Quiz Level
Oksi-84 [34.3K]

Answer: x= 63, y= 27

Step-by-step explanation:

x and angle measure 117 are a linear pair. They sum to 180.

117+x= 180. Subtract 117 from both sides.

x = 63

Looking at the relationship of x and y, the diagram shows that the two together equal 90 degrees. Add the two together and set equal to 90.

63+y= 90. Subtract 63 from both sides.

y = 27
