Evan is painting a stool that has a cylindrical seat and four rectangular prism legs. The seat has a diameter of 8 inches and a height of 2 inches. Each leg is 2 inches by 2 inches by ten inches. How much area will Evan have to paint? Use three point one four for pi. Show your work. @DebbieG
OK, just add up the surface area. There are basically 2 parts: the seat (of which there is 1) and the legs (of which there are 4). So do the seat, and add that to 4 times one of the legs.
It does not say whether he is to paint the BOTTOM of the seat piece, but I would assume so. So the area of the seat is the area of the circle times 2, please the area of the "edge". |dw:1377212655590:dw|
That should be the hard part... the legs are easier. |dw:1377212752371:dw|
Is the formula for finding the surface area of a rectangular prism 2(wh + lw + lh)
