Circumference = 314 inches implies radius = 49.97 inches and so area = 7846.02 sq inches (approx).
First we have to find the radius: 2*pi*radius = 18*pi Divide both sides by 2*pi to find the radius: radius = 9 inches Area of a circle = pi*radius2 Area = pi*92 = 81pi or 254.4690049 square inches
Circumference is 2π times the radius. So, for 14π the radius is 7. Area is πr2, so the area of a circle with radius 7 is 72π, or 49π (153.93).
Circumference = 28.2743339 inches. Area = 63.6172512 square inches.
If you have the circumference: circumference = (pi) * diameter diameter = circumference / (pi) If you have the area: area = (pi) * radius * radius radius = square_root(area / pi) radius = diameter / 2 diameter = 2 * square_root(area / pi)
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
A circle with a radius of 80 inches has an area of 139.6 square feet A circle with a circumference of 40.5 feet has an area of 130.5 square feet
