The radius is 72 inches.
A circle with a radius of 6 feet has a circumference of 37.7 feet.
12 feet. The diameter of a circle is twice its radius.
37.7 feet
The area of a circle is pi.r2 where pi=3.14159... and r=the radius of the circle. So assuming the dimension of 6' given is for the diameter, (giving a radius of 3',) the calculation is: 3.14159x32=3.14159x9=28.27square feet
I believe 8 feet 6 inch radius and 8 feet 6 inch is 8.5 feet Area of circle is pi x radius x radius = pi x 8.5 x 8.5 = 226.98 square feet
A circle with a radius of 6 feet has a circumference of 37.7 feet.
As the diameter of a circle is twice the radius, a circle with a 6-foot radius would have a diameter of 6 x 2 or 12 feet.
Your questions is not solvable the way you wrote it. If you mean, "What is the radius of a circle with a diameter or 6 feet?" , then the answer is 3 feet. Reason is because the radius of a circle is half of its diameter.
If the diameter of a circle is 12 feet then its radius is 12/2 equals 6 feet
If 6 feet 6 inches is its diameter then its radius is 3 feet 3 inches
12 feet. The diameter of a circle is twice its radius.
The radius of a circle is half the diameter → radius = ½ × 12 ft = 6 ft.
The circumference of a circle with a radius of 6 feet is about 37.7 feet. (C = r x 2 x Pi)
