Circumference equals pi times diameter; so C = 84*pi or about 263.9.
For any circle . . .Diameter = circumference/pi .
circumference = 84*pi
84 units x 3.1416 = 264 units (approx)
the combined diameter of all the outer planets is 363,546 kilometers, or 84% the diameter of the sun.
The circumference of a circle is calculated using the formula C = π*d, where C is the circumference, π is a constant approximately equal to 3.14159, and d is the diameter of the circle. In this case, the diameter is 84 inches. Plugging this into the formula, we get C = 3.14159 * 84 = 263.89356 inches. Therefore, the circumference of a circle with an 84-inch diameter is approximately 263.89 inches.
A circumference of 263.89 cm
The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi
Diameter = 84 in Radius = 42 in = 3.5 feet Area of circle = pi x r x r = 3.1415 x 3.5 x 3.5 =38.483 square feet
If you are saying the diameter of a cup is 8 cm and 4 mm and you want to know what that is in mm, the answer is 84.
84
Geologists and civil engineers classify rock fragments based on their size. A small piece of rock may be gravel (2-84 mm in diameter), a cobble (64-256 mm in diameter) or a boulder (>256 mm in diameter).
