Please help me! I did my math homework, but I don’t know what went wrong.
I can’t draw the figure that I am trying to find the surface area of for you, so please go to: http://weedenb.victorschools.org/2013%20Review/chapter%208%20Measure%20figures.pdf and look at number 11. The formula my teacher gave us for figuring it out is (2𝜋rh + 2𝜋r²)divided by 2 for the half cylinder, and for the rectangular prism the formula she gave us is 2lw + 2lh + 2wh. Then we were told to add both answers. Maybe I input wrong #’s?: I input 8 as the radius and height, 30 for length, and 16 for width. I did the formula twice on the calculator, and both times I got 2,098.1 -- which isn’t one of the answers. Please help me figure this out. Thank you so much!
