If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
The radius is one half of the diameter. If the diameter is 20, the diameter is 10.
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
because the chord can be determine by the diameter and the diameter can be determine by the chord.
Diameter of circle = 2 * Radius of the circle.
5,541.77 square cm.
If you take pi as 22/7 the the circumference is 242 cm.
84cm
2.76 Feet
Exactly as in the question 84
120 cm = 1.2 m
56 cm.
84cm² area= l x w = 12 x 7 = 84cm²
84cm = 33.07 inches.
2 feet 9.1 inches.
It is: 58.4cm x 84cm
84cm is 2 ft 9.07 inches or 33.07 inches.
