The formula for the circumference of a circle is 2*pi*radius or pi*diameter. In this case, it's 128=pi*d. Solve for d, and you get 40.74 feet.
Diameter- 128 / pi = 40.7436654 or 41 feet, I had this on my homework, do you know how to show the work though? Tricky.
Circumference=2Pir so 64 is Pixr and the radius is 64/Pi
Height of triangle is 8 inches or 0.75 feet and so base of triangle is 128 feet because 0.5*0.75*128 = 48 square feet
Minor axis = 20, major axis = 57 Perimeter of ellipse = 128 cms.
The circumference of a 128-foot diameter circle is: 402.12 feet.
diameter = 128/pi
It is a simple Algebra question. The answer is 401.92.
If the circumference is 128 feet, the radius is 20.37 feet. If the diameter is 128 feet, the radius is 64 feet.
128 divided by pi (approx. 3.1415927) = about 40.743 feet.
Approx 12.8 inches.

128=2πr 128/2π=r r=20.37 Diameter is equal to twice radius Therefore 20.37 times 2 40.74
It is: 128/4 = 32 which is a side of the square and so 32*pi is the circumference of the circle
circumference = 2 times pi times r OR pi times d diameter = 60 inches pi = 2.1415927 circumference = 2.1415927 x 60 = 128.4956 inches (approximately 128 1/2 inches)
If the circle's circunference is 128 then radius is 128/2pi = about 20.372 inches
