The circumference of a circle is 2[tex] \pi [/tex]r.
If you plug in the numbers, you get 50[tex] \pi [/tex] : 2[tex] \pi [/tex]r.
Then you divide 50 from 2, the pi's will cancel each other out, and you get 25. Your radius is then 25 units.
The area of a circle is [tex] \pi [/tex]r², and if you plug in the numbers, you get A: [tex] \pi [/tex](25)².
Then you do the math and the answer would be: 625[tex] \pi [/tex] units²
If it needs to be in none-pi form, it would be: 1,963.5 units²
