Answer:
The approximate length of the radius, r is 12 inch.
Step-by-step explanation:
Given:
A circle P is given having circumference C,
C = 75 inch
pi = π = 3.14
radius = r
To Find:
radius = r = ?
Solution:
Circumference:
In geometry, the circumference (from Latin circumferens, meaning "carrying around") of a circle is the (linear) distance around it.
That is, the circumference would be the length of the circle if it were opened up and straightened out to a line segment.
Formula is given as

Substituting the values we get
75 = 2 × 3.14 × r
∴ 
We approximate radius to
radius = 12 inich
I believe it's A. Sometimes you have to take an educated guess.
Is the equation2x2(9x+2-16) if so you would do -16+2 first which is -14
Then multiply 2x2 equals 4
4(9x-14)
Multiply the 4 to 9x and -14
You get 36x-56
I think it is 2.8, If not sorry!
