To find the circumference of a circle when given the diameter, you can use the formula C = πd, where C is the circumference, π is pi (approximately 3.14159), and d is the diameter. Given the diameter of 84cm, you can plug this into the formula to get C = 3.14159 * 84 = 263.893cm. Therefore, the circumference of the circle is approximately 263.893cm.
If you take pi as 22/7 the the circumference is 242 cm.
The area of a circle with a diameter of 9.4 m is: 69.4 m2
If the area of a circle is 8pi, its diameter is: 5.657 units.
Assuming a diameter of 5 inches.The area of this circle is: 19.63
