So we are going to find the total surface area of this figure.
00:11
First thing that we are going to find though is going to be the surface area of each of these sphere ends.
00:26
So the formula for a sphere is going to be 4 times pi times our radius which our diameter is 12.
00:44
So half of 12 is going to be our radius.
00:48
So 6 squared, so 4 times pi times 6 squared is going to be 452 .39 feet and that is going to be squared.
01:22
And that is for both sides combined.
01:28
So for just one side it is going to be 226 .20 feet squared due to the way the decimal falls.
01:52
So that is combined and that is single.
01:56
And then for our cylinder, the cylinder is going to be 2 times pi times the radius which we know is 6 times height which is 15 plus 2 times pi times 6 squared.
02:39
So this has a bit more math that is going to be going into it.
02:43
So this one i am going to be doing piece by piece.
02:47
So 2 pi times 6, 2 times pi times 6 times 15 has brought me to 565 .4866.
03:19
It is only asking for hundredths place but i am going to bring it out a couple of extra decimal places because i am going to be working with this in two separate pieces to start with...
