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.
Circumference=2Pir so 64 is Pixr and the radius is 64/Pi
128' x 36' = 4,608 square feet.
Its height is also 16 feet because: 0.5*16*16 = 128 square feet
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
The circumference of a 128-foot diameter circle is: 402.12 feet.
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.
diameter = 128/pi
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.
It is a simple Algebra question. The answer is 401.92.
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=2Pir so 64 is Pixr and the radius is 64/Pi
Approx 12.8 inches.
If the circle's circunference is 128 then radius is 128/2pi = about 20.372 inches
A 128 inch circumference would imply a radius of 20.4 inches - a regular bicycle wheel, for example.
