9.42 inches
No!
It should be an infinitesimally small fraction, since a circumference is a curve and the base of a parallelogram is a straight line.
The base has a circumference of 93 miles
9.42 inches
9.4 kms at its circumference
A cone does not really have a base but if you find the circumference of the bottom that is the base.
base by circumference = area
take the circumference of the base times the height
C = 2 pi r
Find the radius by dividing the circumference by 2pi then find the area of the base and multiply it by the height
The ratio of C to D will equal pi. This is based on the known formula for the circumference of a circle. D = Diameter of the circular base of a cylinder (independent) C = Circumference of the circular base of a cylinder (dependent)
C = 2 x pi x radius
