if the diameter is 7 metres then
(7/2)2 x pi = 38.4845 square metres
A 7-meter diameter circle has an area of 38.5 square meters.
153.94 square meters
A circle with a radius of 7 meters has an area of 153.94 square meters.
38.48 square meters.
The radius is 7 meters.
.7 square meters or .7 meters squared
To find the area of a rectangle, you multiply its length by its width. In this case, the length is 7 meters and the width is 4 meters. Multiplying 7 by 4 gives you an area of 28 square meters. So, a rectangle that is 7 meters by 4 meters has an area of 28 square meters.
The area is 38.485 square meters.
7 x 10 = 70 square meters.
There are about 38.48 square feet in a 7' diameter circle
Using 3.14 as Pi the area of circle is: 153.86
140 square meters (7 x 20 = 140).
