Answer:
It is the second choice.
Step-by-step explanation:
Divide both side by pi r squared. Boom.
36 3/4 = 36.75
36 3/8 = 36.375
37 1/2 = 37.5
36 5/8 = 36.625
(36.75 + 36.375 + 37.5 + z) / 4 = 36.625
(110.625 + z) / 4 = 36.625
110.625 + z = 36.625 * 4
110.625 + z = 146.5
z = 146.5 - 110.625
z = 35.875 or 35 7/8 <===
Glad you asked this question! Over the years of working with my professor we learned that if phs= 5 (constant) times the j to the power of 2 you will get the formula or polynomialic equation. It quite fascinating and due to using his equation the answer in fact is "c". Cheers
Answer:
Approximately 7.16 in
Step-by-step explanation:
Hi there!
Area of a circle equation: 
where r is the radius
Plug in the given area 161 in.²
Divide both sides by π to isolate r²
Take the square root of both sides to isolate r
Therefore, the radius of the circle is approximately 7.16 in.
I hope this helps!
