r = 4.5 feet
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.
the diameter of a circle with the radius of 9m is 18m
the radius of a circle is half the diameter, so half of 1.8 is .9. The radius is .9km.
The diameter is always double the radius so in this case, it is 18cm
The answer is 9
The diameter of a circle is twice the radius. A circle with a radius of 9 would have a diameter of 18. (9*2=18).
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.
A circle with a radius of 9 inches has a circumference of 56.55 inches.
A circle with a radius of 9 feet has an area of 254.47 square feet.
The term "radius" refers to the distance from the center of a circle to any point on its circumference. If you have a circle with a radius of 9 meters, it means that every point on the edge of the circle is 9 meters away from the center. Therefore, the radius of this circle is simply 9 meters.
The radius is 1.43
If a circle has a circumference of 18pi, the radius is 9.
the diameter of a circle with the radius of 9m is 18m
The radius is about 1.432 units.
Area of a circle of radius r = πr2Area of circle of radius 9 In = π(9)2 = π x 81 , putting value of pi we get= 3.14159625 x 81 = 254.46 sq. In
The area of a circle with a radius of nine centimeters is: 254.5 cm2
the radius of a circle is half the diameter, so half of 1.8 is .9. The radius is .9km.
