So this question asks at what pressure will the balloon burst and gives us the surface area at which it will burst.
00:08
And surface area is equal to 4 pi r squared.
00:12
And the surface area they give us is 1257 centimeters squared.
00:17
So if we divide this by 4 pi and take the square root, we get our r to be equal to 10 .00 centimeters.
00:27
And now that we have our r, we can find our volume, v equals 4 pi, and we get our r to be equal to 10 .00 centimeters.
00:31
4 thirds pi r cubed.
00:35
And so we plug in our 10 .00 centimeters for r.
00:38
And we get that our volume is 4190 .6 centimeters cubed, which is equal to 4190 .6 milliliters.
00:50
So we divide by 1 ,000 to get into 4 .106 liters.
00:58
And so now that we have our 4 .1906 liters, we can use the relation p1 v1 over t1 equals p2 v2 over t2...
