The area of a circle is figured out using the formula
Now, the circle we are given has a radius of 9cm. So, the area of the circle would be:
Area = 3.14 x (9)2
= 3.14 x 81
= 254.34 cm2
The area of the circle in question is 254.34 cm2
The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).
radius = 18/2 = 9 cm
Radius is half the diameter. 18 / 2 = 9 Answer: 9.0 cm
To calculate the radius is very easy, the formula is d/2 where d is diametre. therefore according to d/2 = 9cm/2 which is equals to 4.5 cm Result : the radius of a circle with a diameter of 9 cm is 4.5 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
A circle with a radius of 9 cm has an area of 254.47 square cm
To find the diameter of a circle with an area of 254 cm², you first need to calculate the radius. The formula for the area of a circle is A = πr², where A is the area and r is the radius. So, 254 = πr². Solving for r gives you r ≈ √(254/π) ≈ 9 cm. The diameter of a circle is twice the radius, so the diameter of this circle is approximately 18 cm.
pie x 4.5 squared
The exact area = pi*32 or 9*pi square cm
The area of a circle with a diameter of 9 inches is: 63.62 square inches.
A circle with a diameter of 9 yards has an area of 63.62 square yards.
A circle with a radius of 4.5 cm has a circumference of 28.27 cm
The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).The area of a circle with a diameter of 9 feet is 63.6 sq ft (approx).
28.27 cm
A circle with a diameter of 18 cm has a radius of 9 cm, since the radius is half the diameter. The circumference of the circle can be calculated using the formula (C = \pi d), which gives approximately 56.55 cm. The area can be found using the formula (A = \pi r^2), resulting in approximately 254.47 cm². This circle represents a two-dimensional shape where all points are equidistant from the center.
