Divide the diameter by 2 to get the radius. Then use the standard formula for the area of a circle (area = pi x radius2).
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)
The area of a circle is calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. Given a diameter of 40 meters, the radius is ( r = \frac{40}{2} = 20 ) meters. Therefore, the area is ( A = \pi (20)^2 = 400\pi ) square meters. In terms of ( n ), it can be expressed as ( A = 400n ) if ( n = \pi ).
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
To find the circumference of a circle, you can use the formula ( C = \pi \times d ), where ( d ) is the diameter. Given that the diameter is 20 meters, the circumference would be ( C = \pi \times 20 \approx 62.83 ) meters. Thus, the circumference of the circle is approximately 62.83 meters.

The formula for the area of a circle is A = πr^2, where r is the radius of the circle. Since the diameter is 20 meters, the radius is half of that, which is 10 meters. Plugging this into the formula, we get A = π(10)^2 = 100π square meters. Therefore, the area of the circle with a diameter of 20 meters is 100π square meters.
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
The area of a circle is calculated using the formula ( A = \pi r^2 ), where ( r ) is the radius. Given a diameter of 40 meters, the radius is ( r = \frac{40}{2} = 20 ) meters. Therefore, the area is ( A = \pi (20)^2 = 400\pi ) square meters. In terms of ( n ), it can be expressed as ( A = 400n ) if ( n = \pi ).
If the diameter of a circle 20 cm is tripled the area will increase from 314.2 cm2 to 2,827 cm2
To find the circumference of a circle, you can use the formula ( C = \pi \times d ), where ( d ) is the diameter. Given that the diameter is 20 meters, the circumference would be ( C = \pi \times 20 \approx 62.83 ) meters. Thus, the circumference of the circle is approximately 62.83 meters.
The diameter of the circle works out as 20 units to the nearest whole number
