How to find surface area of cone

It's a very good and perfect app for maths solution and it also shows the step by step solving problems. The app is very nice but it struggles to solve some problems, thanks, you really helped me, this actually helps me a lot and I get to finish problems faster and understand them better than how my teacher shows me.

Other wise, it's a really good app. Fast, reliable and simple. If your tired of reading books and searching the web for a guide, this one may be your best assest. This really helps when I'm struggling with specific problem but I do wish there was geometry because I'm really having a hard time with it.
