The radius of a circle with a circumference of 13 feet is: 2.069 feet.
A = 530.9
radius in feet = 13/(2*pi)
Circles have diameters, so we will assume from your question that it is a circular flower bed. Square feet is a measure of area. Cubed feet is a measure of volume. You need the area of the flower bed that has a diameter of 13 feet. To find the area of a circle you use the formula Area = pi * radius squared Pi is approximately 3.14 The radius of a circle is one half of the diameter of a circle. In your case 13/2 = 6.5 A = pi * r2 A = 3.14 * (6.5)2 A = 132.665 square feet
r = ~2.07 feet
1.15 feet
The radius of a circle with a circumference of 13 feet is: 2.069 feet.
A circle with a radius of 13 units has an area of 530.93 square units.
A circle that has a radius of 6.5 feet. Area = pi*radius2
A = 530.9
The circumference is about 81.7 feet.
The circumference is about 81.7 feet.
radius in feet = 13/(2*pi)
The area of a circle, if it has a diameter of 13 feet, is: 132.7 square feet.
