Area of a circle = piRsquared = 3.14 x 80 squared = 20,096 square meters.
Circumference of a circle = π × diameter = π × 80 mm = 80π mm ≈ 251 mm
if width is equal to W and length is equal to L, then W x L = 80 L = W +2 so W x (W+2) = 80 solve to find W=8 and L= 10

A square with an area of 400 square units has a perimeter of 80 units.
A=400 s=20
The area of a circle is: pi times radius^2
If the radius of a circle is 80 inches, then the area of the circle is 139.6263 square feet. (rounded)
r = 5.0463
A circle with a radius of 80 inches has an area of 139.6 square feet A circle with a circumference of 40.5 feet has an area of 130.5 square feet
It is: 80/360 times 25pi = 17.453 square meters rounded to 3 decimal places
It is: 80/360 times 25pi = 17.453 square meters rounded to 3 decimal places
1 acre = 43,560 square feet 80 acres = 3,484,800 square feet area of a circle = (pi)radius squared 3,484,800 divided by pi = radius squared square root of 1,109,244 = radius 2 times 1053.2 = 2106.4 feet is the approximate diameter of an 80 acre circle of land
The diameter of a circle is twice length of a radius, because it is basically two radii (plural of radius) joined together so they form a continuous line across the circle. If you multiply the length of the radius, 40 meters, by 2, then you get the length of the diameter, 80 meters.
Remember the circle equation C = pi d This equation has come to us from Classical Antiquity. pi = ~ 3.141592. d = 80 m Hence C = 3.141592 X 80 m = C = 251.32744123.... m C ~ 251.3 m NB Also remember the other circle equation for area A = pi r^(2) , where 'r' is the radius of the circle ( d/2).
