Function can help us, as we can apply with every integer in input values, & we get ouput values as the result.
Hope this helps!
Answer: Look at the picture ⬇️
For this case we have that by definition, the area of a circle is given by:
Where:
r: It is the radius of the circle
According to the data of the statement we have that the circle has a radius of 
Substituting in the formula we have:
So, the area of the circle is 
feet squared
Answer:
Option D
Answer:
a=69
b=133
c=116
d=93
e=86
Step-by-step explanation:
<u>first start by finding angle a:</u>
angles in a triangle add up to 180 so we can simply do 180 - 40 - 71 = 69
<u>to find b:</u>
b is on a straight line so we can do 180 - 133 = 47
<u>to find d:</u>
d is part of the small triangle on the right of the diagram, we do not know one of the angles but because it is on a straight line we can do 180-140 = 40. Now to find d we can do 180 - 47 - 40 = 93
<u>to find e:</u>
i'm assuming the large triangle containing e is isosceles so we can do 180 - 2x47 = 86
therefore c is 116 as its the only answer left - hope this helps
