Who's Yhe Math Whiz?
Hey I need to figure square footage of a dome's surface area. The dome is 58' tall to the center of the dome and 112' in diameter at the base. Anyone know the formula to figure this:s: I tried to get a hold of my daughter who is a math whiz but she must have classes today and I haven't heard from her. It's kind of embarrassing having to ask your kids things like this so if someone can help me I can tell her I was just calling to see how every thing is going:w2::tu:

Howdy Jazz,
Formula for Square footage of a dome is 2 x pi x r x r So in your case it would be 2 x 3.1415 x 56 x 56 Resulting in 19,703.488 square feet. |

Maybe this next weekend you should try to slip on over to my place at the lake:tu: Do a little fishin and a little :c::c::c: |

It would actually be 2 x pi x Radius(at the ground) x Height of the dome.
2 x 3.14 x 58 x 56 = 20407.786 sq. ft. MMMMMMM Pie..... |

How many yards of concrete will it take to fill a Big Cone 50 Foot Tall with a 10 foot opening that's 1/3 full of rocks? :s:
That was a real question on my entry test at work |
32.32
I had to look that formula up. lol |
Well, someone needs a little help on the spelling end as well. :D

:humm:Maybe I'm just having a brain fart here but a perfect sphere would be height is equal to radius correct? so since this isn't a perfect sphere because height is 58' and radius is only 56' that wouldn't be a correct square footage , would it?:s:

I will have to see what the weekend brings, been working most weekend driving semi trying to save up money for house downpayment.:argh: It's a LONG process but it's getting close. I will give you a call some time, would love to see you and the little puppy sometime before everything closes up for winter. |
