Convert 14° into radians manually (no calculator) please show work. Thank you in advance!!
Inessa [10]

1 degree is \dfrac\pi{180} radians. So 14 degrees is \dfrac{14\pi}{180}=\dfrac{7\pi}{90} rad.

Easy way to remember this: one complete revolution in a circle is 360 degrees. But it's also 2\pi radians. So the conversion rate is

\dfrac{2\pi\,\rm rad}{360^\circ}=\dfrac{\pi\,\rm rad}{180^\circ}

i.e. for every \pi radians there are 180º.

Gnesinka [82]

Answer:

Step-by-step explanation:

Area of A is 50 cm ^2

length of A is 10

Area of B is 50/2 cm^2 or 25cm^2

area for all rectangles is length * width

so area of B divided by length of b is width of b

25/10 = 2.5

width of b is 2.5

We are given with two distances: 5,880,000,000,000 miles and 15.8 light-years. we convert first the light-years distance through the speed of light : 3 x 108 m/s. v = d/t; d = 3x10 8 m/s * 15.8 light years * 31536000 s = 1.4948 x1017 m = 9.28829 x 1013 miles. The difference thus is 8.70029 x 1013 miles
