Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
The area of a circle when the diameter is 30 inches is: 706.9 square inches.

Divide the circumference (38") by Pi (about 3.1416) to get the diameter in inches.
diameter of the circle = 30/pi = 9.549 inches to 3 dp
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!
Remember that the formula for the circumference of a circle is 2πr, with r being the radius. So 2πr is 33. we can divide this number by pi to get the diameter. According to a calculator, 33 / π = 10.50423. Now the formula for the area of a circle is πr2. So we need to divide 10.50423 by 2. The result is 5.25211. This is r. π(5.25211)2 = 86.65987. So the area of a circle with a circumference of thirty three units is 86.65987 units.
The area of a circle when the diameter is 30 inches is: 706.9 square inches.

there are no meters in thirty centimeters. the question should be "how many centimeter are in a meter"...
