The area of a circle is (pi) times (the radius)2. The radius of the given circle is 1/2 of the diameter = 20m. Area = (pi) times (20)2 = 400(pi) = 1,256.64 square meters(rounded)
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
314 ft2
Area of circle: pi*20^2 = 400*pi square units
Using 3.14 as Pi the area of circle is: 1256.0
Oh, dude, you're hitting me with the math questions! Okay, so the area of a circle is π times the radius squared. Since the diameter is 20 meters, the radius is half of that, so 10 meters. Plug that into the formula, and you get an area of 100π square meters. So, like, grab a tape measure and start marking out that circle, or just trust me on the math, whatever floats your boat.
If the circumference of a circle is 62.8 meters the diameter is: 20 meters.
The area of a circle with a diameter of 20 cm is: 314.2 cm2
If the area of a circle is 20 square inches the diameter is: 5.046 inches.
The area of a circle is (pi) times (the radius)2. The radius of the given circle is 1/2 of the diameter = 20m. Area = (pi) times (20)2 = 400(pi) = 1,256.64 square meters(rounded)
A cylinder with a height of 20 meters and a diameter of 10 meters has a surface area of 785.4m2
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
The diameter of the circle works out as 20 units to the nearest whole number
314 ft2
314 ft2
Area of circle: pi*20^2 = 400*pi square units
Oh, isn't that a happy little question! If the area of a circle is 100π, we can use the formula for the area of a circle, which is πr^2. So, 100π = πr^2. By solving for the radius (r), we find that the radius is 10 units. And since the diameter is just twice the radius, the diameter would be 20 units.
