area is A=pi x R2, so 3.14 x 2(2.50)=15.7 the formula is a = pi x r squared . not r x 2 r = d / 2 ie 2.5/2 = 1.25 squared

How do you find the radius of a circle inside a square?
The same as half the side of the square, as the radius of the circle is half its diameter, and the diameter of the circle is equal to the side of the square.
How many square meters in a circle 55 meters in diameter?
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 55 meters, the radius, which is half the diameter, will be 25 meters.So to solve for the area (A) of this circle:A = pi x r2 = 3.1416 x 25m x 25m = 1963.5m2 = 1963.5 square meters.
How can you find the area of a half circle with a diameter of 18 meter?
Area = (pi*92)/2 127.2345025 square meters
What is the approximate distance around the half circle with a diameter of 64 meters?
The circumference (full circle) is the diameter multiplied by pi. For the "half-circle", you would have to divide that by 2.
If the diameter of a circle is 10 meters what is the area in square meters?
The formula for the area of a circle is A = pi x r2 where r is the radius. If the diameter of the circle is 10 meters, then the radius is half that amount or 5 meters. Plug that value into the formula for r, using 3.14 as an approximation for pi. The area is 3.14 x 52 or about 78.5.
How many square meters in a circle 4.2 meters in diameter?
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.
How many square meters in a circle 55 meters in diameter?

If the diameter of a circle is 1.3x10 meters then what is the radius?
Half of that.
How can you find the area of a half circle with a diameter of 18 meter?
Area = (pi*92)/2 127.2345025 square meters
What is the circumference of a circle with a diameter of 4 and a half meters?
14.13

How do you work out the area of a circle in a square?
The formula for the area of a circle is pi x radius2. The radius is half the diameter, and the diameter of an inscribed circle is the same as the length of a side of the square.The formula for the area of a circle is pi x radius2.

What is the area of a circle with a diamerer of 24 meters use 3.14?
area of a circle = pi*r^2 with pi being 3.1415926535..... that is the ratio between the diameter of the circle and it's circumference. r stands for radius (half the diameter if you didn't know) so for this circle to find the area all you have to do is 12 (half of 24 the diameter to find the radius) , then square it (144) then times it by pi which equals approximately 452.39 meters^2
What is the area of a half circle with a diameter of 1600?
1,010,000 square units.
What is the area of a half circle with diameter of 155?
It is 9434.6 square units.
