Question 445582: I think I am doing this wrong because I got an answer 36 pi cm2. But my teacher marked it off as wrong. I looked it up online and people gave the same answer. Did my teacher just mark it off wrong by accident? The question is: find the surface area of the hemisphere with radius 3 cm in terms of pi.

Question 445763: find the surface area of the prism to the nearest hundreth. the bases are right triangles. to the left of the first base next to the right triangle symbol it is the number 3.at the bottom of that base it is 4. and then on the hypotenuse of that triangle it is 5. and the height is 3.5. i found the lateral area first and used the formula LA=ph i got (4+3+5)(3.5)and that came to 42. i then used the formula SA=LA+2B(area of the base). i did 42+2(4(multiplied)by 4) and got 74. the quiestion is multiple choice.
A.)30.5
B.)54
C.)49.45
D.)52.44
i wouls like yo know what i am doing wrong thank you for your time.

Question 446710: Thank you for answering my question before, but my teacher said it was still wrong. The main word in the equation is 'hemisphere' she said....so now I am very confused =(. The question is: find the surface area of the hemisphere with radius 3 cm in terms of pi. it is not 36 pi cm 2.

Question 448933: I have 2 questions: determine the volume and the surface area of the a three-dimensional cube that is 7cm,7cm,7cm. I got as far as determining the formula for a cube was: v= s 3
sa= 6s2 but I am sure this is wrong.
Please help.
The second question is: determine the volume of a large circle of 12cm, with a smaller circle inside of it that is 6cm? I do not even know where to start on this or even how to show all of my work.
Thank you....
