What is the area of a circle if it has a diameter which is 18 feet long?
The area of a circle is equal to πr2 where π (pi) is equal to approximately 3.142 and r represents the radius of the circle. Because the question gives you the diameter and not the radius you have to use the measurement of the diameter to calculate the radius. Remember that the radius is equal to half the diameter. So if the diameter is equal to 18 feet, then the radius of this particular circle is equal to 9 feet. Plugging this into our equation for area we get: area = π(92) area = 3.142(81) area = about 254.5 ft2 (don't forget that the answer is in squared feet not just feet)
If a radius of a circle is 9mm what is the diameter?
Diameter = 2 x radius = 18 mm .
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 diameter of a circle with a radius of 9Cm?
r= 9 so diameter is 2x the radius =18 cm
If a circle has a radius of 9 cm how long is the circle's diameter?
The diameter is always double the radius so in this case, it is 18cm
What is the radius of a circle whose diameter is 36 feet?
Diameter is twice the radius, so 18 feet.
What is the diameter of a circle with a 9 radius?
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).

If the diameter of a circle is 36 what is the radius?
Radius is half the diameter. 18 is the answer.
What is the radius of a circle with a 36cm diameter?
It's 18 cm. The radius is half the diameter of a circle. Half 36 cm is 18 cm.
What is the radius of a 36 diameter circle?
Radius is half the diameter. 36/2=18
What is the radius of a circle if its diameter is 36 cm?
It is 18 centimeters because your radius is exactly half of the diameter in any circle
If a radius of a circle is 9mm what is the diameter?
Diameter = 2 x radius = 18 mm .
What is the diameter if the circumference is 113 feet by 1 inch and the radius is 18 feet?
If the radius is 18 feet - then the diameter is 36 feet. The circumference measurement is irrelevant !
What is the radius of 18 inches?
If the diameter of a circle is 18 inches then its radius is 18/2 = 9 inches
If the diameter of circle z is 18 cm what is the radius?
radius = 18/2 = 9 cm
What is the diameter of a circle with a radius of 9Cm?
r= 9 so diameter is 2x the radius =18 cm
