A circle with a radius of 9 feet has an area of 254.47 square feet.
A circle with a radius of 10 feet has an area of 314.16 square feet.
The radius is 9 feet.
A circle with a radius of 7 feet has an area of 153.94 square feet.
Area of the circle in square feet = pi times radius squared
Square feet are square feet. There is not a measure called radius square feet.
To convert radius miles into square miles, you would need to use the formula for the area of a circle: A = πr^2, where r is the radius. Square the radius value, then multiply it by π (approximately 3.14) to get the area in square miles.
A circle with a radius of 14 feet has an area of 615.75 square feet.
Radius of circle: square root of (64/pi) = 4.5135166683 feet
The area of a circle with radius r feet is pi*r*r square feet.
If the radius of a circle is 80 inches, then the area of the circle is 139.6263 square feet. (rounded)
The area of a circle with a radius of 3 feet is: 28.27 square feet.
A circle with a radius of 6.8 feet has an area of 145.27 square feet.
A circle with a radius of 2.00 feet has an area of 12.57 square feet.
A circle with a radius of 35 feet has an area of 3,848.45 square feet.
The 4' x 4' figure has an area of 4' x 4' = 16 square feet. The area of a circle is pi times the square of the radius. If a circle has an area of 16 square feet, then pi x r2 = 16 ft2. We'll take the 16, divide it by pi and the answer will be the square of the radius. And 16/pi = about 5.093 square feet and the square root of that is about 2.257 feet. The radius of a circle with an area of 16 ft2 is about 2.257 feet. The diameter of a circle is twice its radius, and in this case, 2.257 feet x 2 will have be the circle with a diameter = 4.514 feet.
The area of a circle with a radius of 4 feet is: 50.27 square feet.
