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 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.
If you triple the radius of a circle, the area will increase by 9. Area is proportional to the square of the radius.
