How many square feet in a five foot diameter circle?
Divide the diameter by 2, to get the radius. Then you can use the standard formula for the area of a circle. As a reminder, that is:area = pi x radius squared
What is the area of a five foot circle?
19.63 square feet.
What is the area of a circle with a radius of five?
Area = (pi) (radius)2 = 25 pi = 78.54 square units (rounded)
Why do people use square feet to measure the area of a circle?
The formula for the area of a circle is A = πr2, where π is pi, which is 3.14159 rounded to five decimal places, and r is the radius of the circle. Radius is half the diameter of a circle. The radius is a distance measurement, such as meters or feet. Suppose you have a circle with a radius of 0.25ft. A = πr2 = 3.14159 x (0.25ft)2 = 3.14159 x 0.0625ft2 = 0.19635ft2 If you look carefully, you will see that the radius, a distance measurement, is squared, so the area of a circle will always be a squared distance measurement, such as ft2, in2, m2, cm2, etc... .
What is the locus of points five units from the origin?
The circle of radius five centered at the origin.
How many square feet in a five foot diameter circle?
Divide the diameter by 2, to get the radius. Then you can use the standard formula for the area of a circle. As a reminder, that is:area = pi x radius squared
The radius of a circle with a ten foot diameter?
Five feet (r = d/2).
What is the area of a five foot circle?
19.63 square feet.
What's the area of a circle with a diameter of one foot nine and forty two hundredths square feet or seven hundred five thousandths square feet?
The radius will be 10.5in or 0.875ft. pi r 2 is 346.36 square feet, not either of the 2 you've listed
What is the area of a circle with a radius of five?
Area = (pi) (radius)2 = 25 pi = 78.54 square units (rounded)
How is radius used in a sentence?
The radius of a circle is the distance from the center to any point on the circle's perimeter. For example, "The garden had a circular fountain with a radius of five feet."
