Radius: square root of (50/pi) = 3.989422804
Diameter: 2*3.989422804 = 7.978845608 or as 8 meters to nearest integer
Circumference : 94.2 meters Area : 706.5 square meters
225pi sq m
Area = (pi*92)/2 127.2345025 square meters
TAKE hanf of 3.25 then square it An you will get 3.0625pie as your exact answer.
The radius of the circle is half of the diameter, so it is 4 meters. To find the area of the circle, we can use the formula A = πr^2. Substituting the value of the radius, the area of the circle is therefore A = 3.14 * (4)^2 = 3.14 * 16 = 50.24 square meters.

Area = pi * radius squared A = pi*r2 diameter/2 = radius 60 meters/2 = 30 meters so, Area = pi(30 m)2 = 2827 meters squared =================
The radius of the circle is half of the diameter, so it is 4 meters. To find the area of the circle, we can use the formula A = πr^2. Substituting the value of the radius, the area of the circle is therefore A = 3.14 * (4)^2 = 3.14 * 16 = 50.24 square meters.
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)
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
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
Circumference= 3.14 x Diameter Area of circle= 3.14 x diameter x diameter
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
