If the basketball is regarded as a perfect sphere then the formula for the volume (V) is V = 4/3πr3 where r is the radius. If the radius is 5 inches then V = 4/3π53 = 500/3π = 523.60 cubic inches (2dp)
The average radius for a basketball is around 4 (4.5) inches.
The diameter of a basketball is about Nine Inches.
If its inner radius is 13 inches, the formula for a sphere is 4/3 pi r^3 13x13x13 is 2197, x pi is 6902 cubic inches, /3, x4 is 9202.76 inches cubed
The inside radius of a basketball goal/hoop is 9 inches.
Using the formula for the volume of a cylinder (V = πr^2h), and substituting the given values, we can find the radius. Rearranging the formula to solve for the radius gives us r = √(V / (πh)). Plugging in the values, we get the radius as √(146 / (10π)) ≈ 2.15 inches.
The circumference of a circle with a radius of 6.74 inches is approximately 42.34 inches. The circumference of a circle is found using the circumference formula: Circumference = 2 * π * radius So, all you have to do is plug in the radius into the formula, and approximate π to be 3.14159.
11.4 inches diameter and the radius was 17
The formula for circumference of a circle is 2πr. Since the radius is 4, the circumference is 8π or approximately 25.12 inches.
I can't tell you exactly, but I can tell you how to estimate the number of dots on a basketball. First, measure a 1 inch square on the surface of the basketball and count the dots it contains. Then use the formula for the area of a sphere, which is: 4PR2, or 4 times Pi times the radius squared. An official men's pro basketball is 9 inches in diameter, so the radius would be 4.5 inches and the formula would work out like this: 4 times 3.14 times 20.25 equals 254.34 square inches. Measure any areas on the basketball that have no dots and subtract that area from the total square inches arrived at above. Now multiply this number by the number of dots you counted and you've got a decent approximation.
A basketball which meets the men's NBA standards has a circumference of 29.5". That gives a radius of 4.695 inches, which we can then put into the formula for the volume of a sphere - 4/3Πr3. That works out at 1.3333 x 3.1416 x 103.4920 = 433.4964619 cubic inches. A volume 100 times greater than that would be 43349.64619 cubic inches and taking that down to a radius by reversing the formula above, we get 3√ 43349.64619 ÷ 1.3333 ÷ 3.1416 = 21.7923 So, a sphere which is 43.5846 inches in diameter (that's just over 3 foot 7 inches across) would be 100 times the volume of a men's regulation basketball.
To figure out how many gallons are in a cylinder you can use the following formula: Volume= pi x radius squared x height then divide that by 231 Note: Measure the radius and height in inches this will give you an answer in cubic inches, the reason for dividing by 231 is that there are 231 cubic inches in one US gallon. Using the above formula will tell you how many gallons your cylinder contains.
