Circumference = 2*pi*r
r(radius) = diameter/2 = 36 in/2 = 18 inches
Circumference = 2*pi(18 inches)
= 113 inches

The circumference is: 36*pi = 113.097 inches rounded to three decimal places
Circumference of any circle = 2*pi*radius or diameter*pi
Consider the straight side as the diameter of a circle, find the circumference of the circle, calculate half the circumference and then add it to the diameter. circumference = pi x diameter = 3.14 x 36 = 113.04 perimeter of semicircle = 1/2 circumference + 36 = 56.52 + 36 = 92.52
36/pi = 11.4591559 feet
The volume of a cylinder 1.5 inches in diameter x 36 inches high is 63.62 cubic inches.
