Perhaps you meant to say area? Circumference is a linear quantity, cm squared is an area.
diameter = 2 x sqrt 324 = 36cm
Circumference is 2 x pi x 18
and area is pi x 18 x 18
Radius of circle: square root of (324/pi) = 10.1554125 cm Circumference of circle: 2*pi*10.1554125 = 63.80833861 or 64 cm to the nearest integer
The radius is 18 cm
FORMULA: (n [squared] -- 3n) / 2 (18 [squared] -- 3 x 18) / 2 = (324 -- 54) / 2 = 270 / 2 = 135 Easy as Pi ;)
Square root of 324 = square root of (81 x 4) = square root of 81 x square root of 4 and that is 9 x 2 = 18 cm
No. 9 x 3 x 12 = 324
Radius of circle: square root of (324/pi) = 10.1554125 cm Circumference of circle: 2*pi*10.1554125 = 63.80833861 or 64 cm to the nearest integer
Assuming it is a circle, it is about 63.8 inches, a square would be 72 inches.
18 squared is 324 182=324
18 squared is 324.
It is 324.
18^2=324
It is: 18 squared = 324
