Well, honey, if the circumference is 72.22 inches, then the radius is 72.22 / (2 * π) ≈ 11.5 inches. And if you want to know the area of a circle with that radius, it's π * (11.5)^2 ≈ 415.62 square inches. Math doesn't have to be boring, darling!
2 inch radius = 12 9/16" circumference & an area of 12.56637 sq. inches.
What is 43 inches? The Area? The circumference? The Diameter? If the diameter is 43 inches than the radius is 21.5 inches If the Circumference is 43 inches than the radius is 6.96 inches If the Area is 43 inches than the radius is 3.7 inches Hope this is helpful :)
Area will be 28.27 inches2 Circumference will be 18.85 inches
Circumference = 31.4 inches, approx. Area = 78.5 square inches, approx.
If the radius of a circle is four inches the diameter, circumference and area are:Diameter = 8 inchesCircumference = 25.13 inchesArea = 50.27 square inches
Circumference = 2*pi*3 inches Area = pi*32 square inches
Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
Area = pi*r2 = 50.265 sq inches Circumference = 2*pi*r = 25.133 inches.
Circumference is pi * r * 2. Area is pi * r2. In your circle, both r * 2 and r2 equal 4. Your radius is 2 inches.
Circumference: 2*pi*3 = 6*pi inches Area: pi*3 squared = 9*pi square inches
If the circumference is 1.59 inches , then the radius should be (1.59/2pi) inches. So , the area will be - (pi)*(1.59/2pi)2 = (1.59)2/4pi
