If the area of one circle is four times as large as a smaller circle with radius of 3 inchesThe radius of the larger circle is?
6 inches pi*32 = 9*pi square inches (smaller circle) pi*62 = 36*pi square inches (larger circle)
What is the circumference and area of a circle with a radius of 3 inches?
Circumference: 2*pi*3 = 6*pi inches Area: pi*3 squared = 9*pi square inches
How do you find the circumfrence of a circle if you have the radius?
the circumfrence of a circle is pi times it's radius squared.
What is the circumference and diameterof a circle with a radius of 9 inches?
A circle with a radius of 9 inches has a circumference of 56.55 inches and a diameter of 18 inches.
The diameter of a circle is 9 inches what is the radius?
Radius = Diameter/2. So in this case 4.5 inches.
If the radius of a circle is 15 inches what is the diameter?
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
If The exact area of a circle is 81pi square inches what are the radius and diameter of the circle explain?
The radius is 9 inches because area of circle is pi*9 squared = 81pi square inches and the diameter is twice the radius which is 2*9 = 18 inches
