Default 2 problems strugglin with

Problem 1- An absent minded person puts an exponential(1) amount of air in a balloon. Find the distribution of the radius of the balloon. Volume of a sphere = (4(pie)r^3)/3.

Problem 2- We take a stick of length 1 and break it into 3 pieces. To be precise, we think of taking the unit interval and cutting at X<Y where X and Y have joint density f(x,y)=2 for 0<x<y<1. What is the probability we can make a triange with the 3 pieces? (can do if no piece is longer than 1/2). Thank in advance for any help.
