Answer:

5.625

Step-by-step explanation:

So first do 112 / 360

Simplify it = 28 / 90 = 14 / 45

So 1.75 is 14 / 45 of the circumference.

The whole circumference is 1.75 * (45 / 14)

So the answer is 45 / 8 = 5.625

The veloctiy of sound in air is given by the equation v=20 times the square root of 273+t where v is the velocity in meters per

Nikitich [7]

So we just need to plug in our values and solve
$v = 20 \sqrt{273 + t}$
we are given v is 369 so we have
$369 = 20 \sqrt{273 + x}$
now we solve for x.
divide both sides by 20
square both sides
subtract 273 from both sides
$369 = 20 \sqrt{273 + x} \\ 18.45 = \sqrt{273 + x} \\ 340.40 = 273 + x \\ x = 67.4$
so a temp of about 67 degrees C
