y=6x^2+5 from x=0 to x=5

I'm just starting to learn about this and am very confused. Can someone show me how to do this. Thanks. I need help.

**Reiny**, Wednesday, May 14, 2008 at 9:22pmAlways make a rough sketch of your problem, here you have a parabola opening upwards with centre at (0,5)

so the area

= integral [6x^2+5)dx from 0 to 5

= [2x^3 + 5x] from 0 to 5

= 2(125) + 25 - 0

= 275
