What is the circumference of a table cloth that is thirty inches across the table top and has a thirty inch drop to the floor?
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!
A circle has a circumference of 94.2 centimeters Its diameter is 15 centimeters which expression can you use to find the approximate value for pi?
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?
The circumference of a 30 ft circle is: 94.2 feet.
The circle has a radius of 30 millimeters. What is the diameter of a circle in centimeters?
The radius of the circle is half the diameter of the circle. 30mm radius would mean 60mm diameter or 6cm.
If the circumference of the disc was 30 inches what is the diameter?
d=9.5541401 in.
