we know that in this problem-----> <span>the circumference of the foundation is 4 times the radius, increased by 114 ft </span>so C=4*r+114------> equation 2 (1)=(2) 2*pi*r=4*r+114------> 2*pi*r-4*r=114-----> r*[2*pi-4]=114---> r=114/[2*pi-4] r=114/[2*pi-4]-----> 50 ft
Putting all the names in a hat and selecting six students because the rest would not have been random because you know who you picked just by looking but if u put names in a hat you don't know who you picked.
