What is the area of a circle with a diameter of 6 in?
The formula for area of a circle is: A = (pi)*r^2 If the diameter of a circle is 6 then the circle's radius is 3. So, A = (pi)*(3)^2 A= 9*(pi) inches squared or A = 28.26 inches squared (rounded)
What is the radius of 18 inches?
If the diameter of a circle is 18 inches then its radius is 18/2 = 9 inches
What is the radius of a 9ft by 9 ft circle?
Since your circle has a diameter of 9 feet (the definition of a "9 by 9" circle), the radius is half of that distance. In this case, your radius is 4.5 feet or 54 inches.
What is the area of a circle with a diameter of 9 inches?
The area of a circle with a diameter of 9 inches is: 63.62 square 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 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
Find the area of a circle with a radius of 9 inches?
254.47 square inches.
What is a circumference of a circle with the radius of 9 inches?
A circle with a radius of 9 inches has a circumference of 56.55 inches.
What is the area in square inches of a circle with diamter of 1.5ft?
The circle's radius is 1.5/2 = 0.75 ft = 9 inches The area of the circle is (pi) times (radius)2 = (pi) x (9)2 = 254.469 square inches (rounded)
What is the area of a 12 inch and a 9 inch circle?
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. For a 12-inch circle, the radius is half of the diameter, so the radius is 6 inches. Therefore, the area of the 12-inch circle is A = π(6)^2 = 36π square inches. Similarly, for a 9-inch circle, the radius is 4.5 inches, so the area of the 9-inch circle is A = π(4.5)^2 = 20.25π square inches.
If the radius of a circle is two inches what is the area and circumference?
2 inch radius = 12 9/16" circumference & an area of 12.56637 sq. inches.
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 circumference of a circle is 18pi inches Determine the area of the circle?
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
What is the area of a circle with a radius of 9 ft?
A circle with a radius of 9 feet has an area of 254.47 square feet.
If the radius of a circle is 9 inches what is the diameter?
18 inches
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 area of a circle with a diameter of 6 in?
The formula for area of a circle is: A = (pi)*r^2 If the diameter of a circle is 6 then the circle's radius is 3. So, A = (pi)*(3)^2 A= 9*(pi) inches squared or A = 28.26 inches squared (rounded)
