Answer:
The perimeter of a circle can be found by using the followinfg expression
P = 2*π*r
where
π = 3.14
r = radius of the circle = half the diameter of the circle
In this case, if we are given the radius, we use
P = 2*π*r
If we are given the diameter, we use
P = 2*π*(D/2) = π*D
1) 27in
radius = 27in
P = 2*(3.14)*(27 in) = 169.56 in
diameter = 27 in
P = (3.14)*(27 in) = 84.78 in
2) 79 in
radius = 79 in
P = 2*(3.14)*(79 in) = 496.12 in
diameter = 79 in
P = (3.14)*(79 in) = 248.06 in
3) 1809 in
radius = 1809 in
P = 2*(3.14)*(1809 in) = 11360.52 in
diameter = 1809 in
P = (3.14)*(1809 in) = 5680.26 in
4) 152 in
radius = 152 in
P = 2*(3.14)*(152 in) = 954.56 in
diameter = 152 in
P = (3.14)*(152 in) = 477.28 in
Answer:

Answer:
B
Step-by-step explanation:
Recall that if two functions, <em>f</em> and <em>g</em>, are inverses, then by definition:
Hence, the graph of f(g(x)) should be simply <em>y</em> = <em>x</em>.
Therefore, our answer is B, as both coordinates are equivalent for all three points.
(x + 8)(y + 3)
x*(y+3) + 8*(y + 3)
x*y + 3*x + 8*y + 3*8
xy + 3x + 8y + 24
So the correct product is = xy + 3x + 8y + 24, I guess the second expression.
I hope this helps.
