Answer:

31.4

Step-by-step explanation:

C = 2πr OR C = πd

But, we need to find r first.

A = \pi r^2\\25\pi = \pi r^2\\\sqrt{25} = \sqrt{r^2} \\r=5\\\\C=2\pi r\\C=2\pi (5)\\C= 10\pi \\C= 31.4

Mathematics help please!!!!!!!!!<br><br> what is -0.0833333333333 converted into a fraction?
VladimirAG [237]

Answer:

- 1/12

Step-by-step explanation:

Let -0.0833333 = x  ---  (1)

Multiply both sides by 10.

-0.833333 = 10x   --- (2)

Subtract (2) from (1),

0.75 = -9x

-9x = \frac{75}{100}

= \frac{3}{4}

x=-\frac{3}{36}

x=-\frac{1}{12}

Therefore, our answer would be (B)
