13 mm. The radius of a circle is 1/2 of the diameter.
Circumference = 2*pi*4 mm or 8*pi mm
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
If the diameter is 25 mm then the circumference is 78.54 mm.
If the diameter of a circle is 5.4mm, then the radius is 2.7 mm. The formula for the area of a circle is PIr^2. So, the area is then 22.9 mm2.
Radius of the circle: 6.28/2*pi = 0.999 mm or about 1 mm
13 mm. The radius of a circle is 1/2 of the diameter.
Well, honey, the radius of a circle is always half of the diameter. So if the diameter is 30 mm, the radius would be 15 mm. It's basic math, darling. Hope that clears things up for you!
Oh, dude, you just gotta divide the diameter by 2 to get the radius, which is 120 mm. Then you square that bad boy to get 14,400 mm². So, like, the area of the circle is 14,400 mm². Easy peasy, lemon squeezy.
It is: 1060/2 = 530 mm
