The circumference or perimeter of the circle has the formula 2*pi*r, where r is the radius of the circle. This could then be easily calculated:
C = 2*pi*r
53.38 = 2*3.14*r
53.38 = 6.28r
r = 53.38/6.28
r = 8.5 ft
Thus, the radius of the circle has a length of 8.5 feet.
I would say she is 4. i hope this helps

Answer:
39 cm
Step-by-step explanation:
using the x component go find 12 cm width and follow the line up until it intersects the graph. then follow that point left to estimate the height at that point to estimate 37.5 but more accurately you can use the given equation y=3.25x and plug in your x of 12 to get y=39
Answer:
A
Step-by-step explanation:
One thing to note is that the side opposite to the angle is taken as perpendicular
If we take 57 as angle then it's opposite side is perpendicular
While if we take 33 as angle x is the perp
