Assuming the balloon is perfectly spherical and that the 12" you state refers to the diameter of the balloon then it is obviously 6". If you can't assume any of the above then your question cannot be answered.
The volume will be 5723 assuming that the balloon's elasticity makes no difference.
Oh, dude, the average PSI of a balloon before it bursts is around 10-12 psi. But like, who really measures the pressure in their party balloons, right? Just blow it up until it pops and call it a day!
Such that there are 12 inches in one foot, there are 12 inch pounds in one foot pound. Therefore, 5 foot pounds is equal to 12 x 5 = 60 inch pounds.
1 cm = 0.3937 inch 1 inch = 2.54 cm
A millimeter, as almost every 12 inch ruler has centimeters and millimeters on the opposite side of where inches are marked.
A circle with a 12 inch diameter has a 6 inch radius.
12 inch
6 inch, because the radius the basically half of the diameter
6 inch
6 inches because the 12-inch softball would be the diameter.
12 inches
12 inch diameter(also 6 inch radius).
It typically takes about 0.5 pounds of helium to fill a 12-inch latex balloon.
The area of a circle is calculated using the formula A = πr^2, where r is the radius of the circle. For a 12-inch circle, the radius is half of the diameter, so the radius is 6 inches. Therefore, the area of the 12-inch circle is A = π(6)^2 = 36π square inches. Similarly, for a 9-inch circle, the radius is 4.5 inches, so the area of the 9-inch circle is A = π(4.5)^2 = 20.25π square inches.
6 inches
The radius of a circle is half of its diameter. Since the diameter of the circle is 24 inches, the radius would be 24 inches divided by 2, which equals 12 inches. Therefore, the radius of a 24-inch circle is 12 inches.
I assume 12 is diameter. If so 12/2 is radius of 6in. 6x6xpi is 113.1squared inches
