Please help me! Will give medal :)
Evan is painting a stool that has a cylindrical seat and four rectangular prism legs. The seat has a diameter of 14 inches and a height of 4 inches. Each leg is 4 inches by 4 inches by eighteen inches. How much area will Evan have to paint? Use three point one four for pi. Show your work.

please help i have this and 2 more questions to finish my class!!

bibby · Answer

The area of the stool is equal to the area of the cylinder seat + 4 leg areas.

First find the length area. You have a rectangular prism measuring 4x4x18

what's the area of that figure?|dw:1396927075789:dw|

anonymous · Answer

288

bibby · Answer

So we have the area of the legs.

Now what is the area of a cylinder with  diameter of 14 inches and a height of 4 inches

Remember that the area of a cylinder is pi * r^2 * h

bibby · Answer

that might not be it actually

anonymous · Answer

umm.. what? ... the area is 615.44

bibby · Answer

yeah that's wrong. find the surface area

bibby · Answer

how'd you get that number?

anonymous · Answer

3.14*radius^2*h... like u said

bibby · Answer

I said those weren't the right formulas. If we're painting the chair, we have to use surface area formulas

anonymous · Answer

ok

anonymous · Answer

@bibby

bibby · Answer

Find the surface area formulas for a rectangular prism and cylinder and apply them

anonymous · Answer

rectangular prism:2(wl+hl+hw)... cylinder:2πrh+2πr2

bibby · Answer

w-4 l-4 h18

anonymous · Answer

ok hold on :)

anonymous · Answer

for rectangular prism its:872........

bibby · Answer

I got 320
2(16+72+72)

bibby · Answer

why would I do your homework? I'm here to give you a guiding hand not give you the answers dear

anonymous · Answer

yea ... but idk i think my calculator is damaged lol.... hold on, so you got 320 for rectangular prism.. so let me do the cylinder

bibby · Answer

2πrh+2πr2
remember that pi is approximated to 3.14
r = 14/2 = 7
h = 4

anonymous · Answer

there u go.... i thought the height was 18.. lol

bibby · Answer

that was for the rectangle

anonymous · Answer

ehh.... i need to learn.... hold on

anonymous · Answer

cylinder:  7817.8464

bibby · Answer

lemme see 
$$\huge 2πrh+2πr^2$$$$\huge 2π7*4+2π7^2$$$$\huge 28*2π+2π49$$$$\huge 56π+98π$$154*3.14=483.56

anonymous · Answer

oh ok... so do i add up the to answers?

bibby · Answer

not exactly. Logically this is what the chair looks like:|dw:1396929281033:dw|
