Nine hundred thirty-four thousandths rounded to the nearest hundredth would be 0.93.
diameter of the circle = 30/pi = 9.549 inches to 3 dp
A hundredth is .01 ...so thirty eight hundredths is .38 That is your answer
Circ = 2 pi r = 60pi = 60 x 355/113 = 188.5" to one significant figure
A second.
30.00
Nine hundred thirty-four thousandths rounded to the nearest hundredth would be 0.93.
Since 32 is an integer, it is already rounded to the nearest fractional part.
The circumference of a circle with a diameter of 30 centimeters is: about 94.25 cm. You can easily do this calculation for other circles by multiplying the diameter by Pi (about 3.1416).
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
Yes
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.
It is 0.35
More11 pi is about 34.557 cm
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!
