Given a circle with an area of 25 pi in^2 <br> What is the exact circumference?

Taya2010 [7]

Answer:

31.4

Step-by-step explanation:

C = 2πr OR C = πd

But, we need to find r first.

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

irina1246 [14]

Answer:

Step-by-step explanation:

If student ticket = 215 then 215 x 3 = 645$

Remaining tickets = 522 - 215 = 307

Total amount = 1228 + 645 = $1873
