A hotel is in the shape of a cylinder, with a circular foundation. the circumference of the foundation is 4 times the radius, increased by 114 ft. find the radius of the circular foundation. use 3.14 as an approximation for pi.
we know that in this problem-----> the circumference of the foundation is 4 times the radius, increased by 114 ft 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
