A = pi * r2so:A = 3.14 * 82 = 200.96 square meters
If the diameter of a circle is 37.3 meters its area is: 1,093 m2
Diameter = Circumference / Pi Diameter = 16 / 3.14 Diameter = 5.095
A cylinder with a height of 20 meters and a diameter of 10 meters has a surface area of 785.4m2
A cylinder with a diameter of 7 meters and a height of 12 meters has a volume of 461.81 cubic meters.
The closest is 16 meters. The actual diameter is about 15.5 meters.
A circle 16 meters in diameter has a circumference of 16*pi or about 50.26 meters.
The answer is 16 meter.
A = pi * r2so:A = 3.14 * 82 = 200.96 square meters
16 square meters, to 2 significant digits. The area of a circle is calculated as the value pi (3.1416...) times the square of the radius of that circle. In this case, where a circle has a diameter of 4.2 meters, the radius, which is half the diameter, will be 2.1 meters. So to solve for the area (A) of this circle: A = pi x r2 = 3.1416 x 2.1m x 2.1m = 15.954456m2 = 16 square meters.
Area of a Circle = Pi * radius squared Radius = Diameter / 2 So, Area = Pi * (16/2)^2 = Pi * 64 = 201.06 m^2 Measurement is in meters squared.
The circumference of a circle with a diameter of 13.4 meters is: 42.1 meters (diameter x Pi = circumference).
Diameter being 22 meters, the area is 380.12 meters
If the circumference of a circle is 62.8 meters the diameter is: 20 meters.
diameter = 220/pi meters
The Sun's diameter is approximately 1,391,000,000 meters in length, which is over 100 times the approximate diameter of the Earth (12,756,200 meters).
The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
