What is the area of a circle whose radius is 18 cm?
Well, darling, the area of a circle is calculated using the formula A = πr^2, where r is the radius. So, plugging in 18 cm for the radius, we get A = π(18)^2 = 324π cm². So, the area of a circle with a radius of 18 cm is 324π square centimeters. Voilà!
What is the area of a circle if the radius is 9?
i believe that it is 18 if the radius is 9 edit: wrong, area = pi*radius^2 so it's 3.1415926535*81=254.469
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
If the diameter of a circle is 36 what is the radius?
The radius of a circle is always half of the diameter. Therefore, if the diameter of a circle is 36 units, the radius would be half of 36, which is 18 units. The formula for finding the radius from the diameter is radius = diameter / 2. So, in this case, the radius would be 18 units.
What is the area of a circle with a diameter of 18 cm?
To find area of a circle, the formula is πr2 where π is pi. Half of the diameter is the radius (r) so you divide 18 by 2 to get the radius (9). then, you square it (multiply it by itself) giving you 81. You then multiply this by pi to get the area. The exact answer is 81π, with a good approximation of: 254.46900494077325231547411404563973361997072134938357149897
What is the area of a circle that has a radius of 18 centimeters?
A circle with a radius of 18 centimeters has an area of 1,017.88 square centimeters.
What is the area of a circle with a radius of 18 inches?
A circle with a radius of 18 inches has an area of 1,017.88 square inches.

What is the area of a circle with a radius of 18?
Area is 1,017.9 units2
A circle has an area 324 pi cm What is the radius?
The radius is 18 cm
If radius of a circle is 18 in what is the area?
The area of a circle can be calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. For a circle with a radius of 18 inches, the area would be ( A = \pi (18)^2 = \pi \times 324 ). This yields an area of approximately ( 1017.88 ) square inches when using ( \pi \approx 3.14 ).
Circle with 18 meter radius what was its circumference?
The circumference of a circle is calculated using the formula 2πr, where r is the radius. In this case, with a radius of 18 meters, the circumference would be 2 x π x 18 = 36π meters.
What is the area of a circle with a diameter of 36 centimeters?
A circle with a radius of 18 centimeters has an area of 1017.88 square centimeters.
What is the area of a circle that has a diameter of 18 cm?
A circle with a radius of 9 cm has an area of 254.47 square cm
What is the diameter of a circle when the area of the circle is 254.34?
Divide the area by Pi. Take the square root of the result. This is the radius. Now double the radius to get the diameter. -> Answer = 18
What is the area of a circle whose radius is 18 inches?
The area is 1,020 square inches.
How many sq. inches in a 18 inch circle?
To find the area of an 18-inch circle, you can use the formula for the area of a circle, which is A = πr², where r is the radius. The radius of an 18-inch circle is 9 inches (half of the diameter). Therefore, the area is A = π(9 inches)² = π(81) ≈ 254.47 square inches.
