![\pi 5^2*10 \pi](https://tex.z-dn.net/?f=%20%5Cpi%205%5E2%2A10%20%5Cpi%20)
apply exponent rule
![=5^2*10 \pi ^2](https://tex.z-dn.net/?f=%3D5%5E2%2A10%20%5Cpi%20%5E2)
![=10*25 \pi ^2](https://tex.z-dn.net/?f=%3D10%2A25%20%5Cpi%20%5E2)
multiply the numbers:25x10=250
![=250 \pi ^2](https://tex.z-dn.net/?f=%3D250%20%5Cpi%20%5E2)
refine to a decimal form
![=2467.40110](https://tex.z-dn.net/?f=%3D2467.40110)
Hope this helps :)
