A circle with a radius of 50 feet has an area of pi*502 = 7854.0 sq ft
A circle with a radius of 50 units has a circumference of 314.16 units.
Area = pi*42 = 50.26548246 or about 50 square cm
The area of a circle of radius 21 is 1386
Area of a circle = pi*radius squared
r = 3.9894
If the sector of a circle has a central angle of 50 and an area of 605 cm2, the radius is: 37.24 cm
A circle with a radius of 50 feet has an area of pi*502 = 7854.0 sq ft
A circle with a radius of 50 mm has an area of 7853.98 square mm
The formula for the area of a circle is A = (pi)r2 pi = 3.142 and r = 50 A = 3.142 x 502 A = 7855
The area of a circle with a radius of 50 km is approximately 7,853 hectares.
If you mean a sector with an arc of 110 degrees and an area of 50 square units Area of all the circle: 360/110 times 50 = 163.'63' square units Radius of the circle is the square root of 163.'63'/pi = 7.2171377402 So the radius of the circle is about 7 units
area of a circle is pi x radius^2 so... pi x 4^2 = about 50 cm
The area of a circle is pi times radius squared
If you have a circular area with a 50-mile radius, the area of the circle is approximately 7,854 square miles (rounded).
A circle with a radius of 50 units has a circumference of 314.16 units.
Area = pi*42 = 50.26548246 or about 50 square cm
