The radius is 2 cm
The formula is: A = PI(r)^2 A circle with a radius of 29 cm has an area of 2,642.08 square cm.
A=Pi(r)2 - A circle with a radius of 4 cm has an area of 50.27 square cm
Using 3.14 as Pi the area of circle is: 379.94
Area circle = π × radius² Area smaller circle = π × (4 cm)² = 16π cm² Area larger circle = π × (10cm)² = 100π cm² → probability inside smaller circle = area_smaller_circle/area_larger_circle = 16π cm²/100π cm² = 16/100 = (4×4)/(4×25) = 4/25.
Area of ANY circle is (pi) x (radius)2 .
The radius is 2 cm
A = Pi(r)2: A circle with a radius of 8 cm has an area of 201.06 square cm.
The formula is: A = PI(r)^2 A circle with a radius of 29 cm has an area of 2,642.08 square cm.
A circle with a radius of 4.8 cm has an area of 72.38 square cm. The formula is: A = PI(r)^2
A=Pi(r)2 - A circle with a radius of 4 cm has an area of 50.27 square 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!
To find the radius of a circle when given the area, you can use the formula A = πr^2, where A is the area and r is the radius. Given that the area is 153.86 cm^2, you can plug this value into the formula and solve for r. 153.86 = πr^2 r^2 = 153.86 / π r = √(153.86 / π) ≈ √49 ≈ 7 cm Therefore, the radius of the circle is approximately 7 cm.
The radius of a circle is half the diameter, so if the circle has a diameter of 2 cm, the radius would be 1 cm.
Area = about 12.57cm2
The area of a circle can be calculated using the formula A = πr^2, where r is the radius of the circle. Since the diameter is twice the length of the radius, the radius of a circle with a diameter of 6 cm is 3 cm. Plugging this value into the formula, we get A = π(3)^2 = 9π cm^2. Therefore, the area of a circle with a diameter of 6 cm is 9π square centimeters.
Area of circle: pi*8^2 = 64*pi square cm
