Volume=4/3(pi)r3
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.
The radius and circumference of a circle are related as C=2*pi*R (* stands for multiplication) where C is the circumference(=12 inches in the given case), R is the radius(to be found out) and 'pi' is a constant whose value is approximately 3.141592654. To find R the formula becomes R=C/(2*pi). Substituting 12 inches for C and the value of 'pi' we arrive at the following result: R or radius=12/(2*3.141592654)=1.909859317 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.
To find the radius of a circle with a circumference of 20 inches, you can use the formula for circumference: C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 20 inches, you can plug this value into the formula: 20 = 2πr. Solving for r, you get r = 20 / (2π) ≈ 3.183 inches. Therefore, the radius of the circle is approximately 3.183 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
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.
To find the radius of a circle when given the circumference, you can use the formula C = 2πr, where C is the circumference and r is the radius. Given that the circumference is 62.8 inches, you can plug this value into the formula: 62.8 = 2πr. Solving for r, you get r ≈ 9.98 inches. Therefore, the approximate radius of a circle with a circumference of 62.8 inches is 9.98 inches.
