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!
You've stated an impossible question. If a circle has a circumference of 94.2 cm, it has a diameter of 30 cm. If it has a diameter of 15cm, it has a circumference of 47.1 cm.circumference = 2 * pi * radius = pi * diameterIf you had stated the question correctly (changed circumference to 47.1 cm OR changed diameter to 30 cm OR changed "diameter" to "radius"), then the answer would be:pi = circumference / diameter = (e.g.) 94.2 cm / 30 cm
The circumference of a 30 ft circle is: 94.2 feet.
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
d=9.5541401 in.
The circumference of every circle is (pi) x (diameter).The circumference of this particular circle is 30 pi.
Diameter = 30/pi inches
diameter of the circle = 30/pi = 9.549 inches to 3 dp
The circumference of a circle with diameter of 30 centimeters is: 94.2 cm (diameter x Pi = circumference).
The circumference of a circle 30 inches in diameter is 30*pi inches
If the circumference of a circle is 30 cm its diameter is: 9.549 cm
The circumference of a circle with a diameter of 30 units of length is pi*30 = 94.2 units. The circumference of a circle with a diameter of 30 units of length is pi*30 = 94.2 units. The circumference of a circle with a diameter of 30 units of length is pi*30 = 94.2 units. The circumference of a circle with a diameter of 30 units of length is pi*30 = 94.2 units.
The circumference of a 30-foot diameter circle is: 94.248 feet.
A circumference of 94.2 units.
circumference = 30*pi feet
Circumference = 30*pi feet
diameter = 30/pi units of measurement
