5ft * Pi = Approximately 15.7ft
The radius of a circle is half the length of the diameter. Therefore, if the diameter is 1 foot, the radius would be 0.5 feet. This is because the radius is the distance from the center of the circle to any point on the circle's circumference, while the diameter is the distance across the circle passing through the center.
The circumference of circle with 2 foot radius is: about 12.57 feet. (c = r x 2 x Pi)
A circle with a radius of 5 units has an area of 78.54 square units.
The radius of the circle is the length between the middle of the circle and any of the sides. It is also half the lenght of the diameter.
5ft * Pi = Approximately 15.7ft
A=3.14x5x5=78.5 sq. ft.
Area of circle: pi*5^2 = 25*pi square feet
NO
The area of a circle is PI times the radius of the circle squared. The radius of a one foot diameter circle it 1/2 or .5 feet. .5 squared is .25 PI is 3.1416 3.1416 times .25 = .79 square feet So, there are about .8 square feet in a 1 foot diameter circle.
Area of a circle = pi*radius squared
the circemference would ge 2 and a half feet
The circumference of a circle of radius 5 is about 31.42
Area of a circle = pi times radius squared
1.5'
A 25-foot radius circle is 1,963.5 ft2
72 foot
