A table which is 90 inch around its outside (circumference) is 28.648 inches (to 3 dp) across (diameter).
If the table is circular, then its circumference is 18.845 (rounded) If it's not a circle, then the circumference can't be calculated knowing only the area.
The circumference of a circle that is 30 feet across is: 94.25 feet (diameter x Pi = circumference).
A circumference of 17.91 cm
Circumference = 72*pi
A table which is 90 inch around its outside (circumference) is 28.648 inches (to 3 dp) across (diameter).
We're assuming the table and cloth are round? The cloth is a circle with a diameter of 90 inches - 30 from the floor to the table, 30 more across the table, and 30 more to get back down to the floor. The circumference of a circle is pi times the diameter. Do the math!
if 4 foot is the circumference then the diameter is 4/pi = 1.27323954
distance or circumference = 15*pi = 47.124m rounded to 3 decimal places
If the table is circular, then its circumference is 18.845 (rounded) If it's not a circle, then the circumference can't be calculated knowing only the area.
The circumference of a circle that is 30 feet across is: 94.25 feet (diameter x Pi = circumference).
The area of a circular table with an 18-foot circumference is 25.783 feet2
