This is missing some information. For instance, it does not say what 84 is. Is it the radius, the circumference? See the link below for a step by step guide to finding a diameter.
Circumference equals pi times diameter; so C = 84*pi or about 263.9.
To find the diameter of a circle when given the circumference, you can use the formula: circumference = π * diameter. Given a circumference of 84 units, you can plug this value into the formula and solve for the diameter. Dividing 84 by π gives you approximately 26.67 units as the diameter of the circle.
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
To determine the amount of fencing required to enclose a circular garden, we need to calculate the circumference using the formula (C = \pi \times d), where (d) is the diameter. For a garden with a diameter of 84 meters, the circumference is (C = \pi \times 84 \approx 263.76) meters. Therefore, approximately 263.76 meters of fencing is required.
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.
