The diameter of a circle is twice the radius.
The diameter of a circle is twice the radius.
The diameter of a circle is twice the radius.
The diameter of a circle is twice the radius.
Diameter is twice the radius, so 18 feet.
The area of a circle is calculated using the formula A = πr^2, where A is the area and r is the radius of the circle. Since the diameter of the circle is 12 inches, the radius would be half of that, which is 6 inches. Converting inches to feet (1 foot = 12 inches), the radius would be 0.5 feet. Plugging this into the formula, the area of a 12-inch circle would be approximately 0.785 square feet.
There are three feet in one yard, so a diameter of two yards is six feet. The radius is half the diameter, so the radius is three feet.
Diameter = 50 inches Radius = 25 inches Area of circle = pi x 25 x 25 = 3.1415 x 625 = 1963.44 square inches which is equivalent to 1963.44/144 = 13.63 square feet
-- 3 feet in the diameter -- 1.5 feet in the radius -- 9.425 feet in the circumference (rounded)
If 6 feet 6 inches is its diameter then its radius is 3 feet 3 inches
40'
900 feet.
Since your circle has a diameter of 9 feet (the definition of a "9 by 9" circle), the radius is half of that distance. In this case, your radius is 4.5 feet or 54 inches.
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.
If the radius is 8 feet then the diameter will be 16 feet.
The area of a circle is pi × r2. pi = 3.141592653589793 5 feet = 60 inches. The radius is half the diameter so the radius is 30 inches. If you plug 30 inches into the formula you get the answer of 2827.4333882308138 inches for the area of the circle.
4 feet. The radius is half the diameter.
12 feet. The diameter of a circle is twice its radius.
A circle with a 1 foot 1 inch radius.
Diameter is 16. The radius is half its diameter
If a circle is 50 feet wide, that means its diameter is 50 feet. The radius of a circle is half the diameter, therefore the answer is 25 feet.
