64 cm
64cm (8cm x 8 sides = 8 x 8 = 64).
It is: 8*8*8 = 512 cubic cm
The radius will turn out to be the square root of the area divided by pi which in this case is about 4.51351666838205 cm
8 (measure of each side) x 8 (total sides of an octagon) = 64cm
50-64cm
64cm 1.4m = 140cm 140cm - 76cm = 64cm
64/7=9.142857142857143
64 cm
You know our secret, you must be killed.
64cm.
32cm, the radius is half of the diameter
It is: 64/4 = 16 cm
64 centimeters is 0.64 meters.
radius = 64/(2*pi) = 10.186 cm rounded to 3 dp
It is: 4*2 = 8 square cm
If you want to add them, it's 12cm, but if you want to multiply them, it's 64cm.
