A circular railroad-crossing sign has a diameter of 30 inches. R XR
Which measurement is closest to the area of the sign in square inches?

To find the area, it is r² times pi. The radius is half the diameter, so divide:

30÷2=15

15²=225×π≈ 706.8583

So, C is the closest to the actual answer (which when rounded, will actually get to the actual diameter).

Step-by-step explanation:

there would be 365 different 4 digit numbers

step-by-step explanation:

i belive that it is 365 because i asked google

+25 = x

step-by-step explanation:

here x is the hypotenuse of a right triangle whose legs are 7 and 24.   by the pythagorean theorem, 7² + 24² must equal x²:

x² = 49 + 576 = 625.   thus, x = +√625 = +25 = x
