What Is The Surface Area Of A Tennis Ball?
Contents
The surface area of a tennis ball is approximately 9.6 square inches. This is the size of a regulation tennis ball.
Introduction
A tennis ball has a surface area of approximately 78.5 square inches. The surface area of a tennis ball is the total area of the ball’s exposed surface. The surface area of a tennis ball can vary slightly depending on the size and type of the ball, but is typically around 78.5 square inches.
The History Of The Tennis Ball
The first-known lawn game played with a ball was Paume, a French game played with the palm of the hand. In time, players wrapped string around their hand to improve hitting power. By the 16th century, rackets (a frame with strings) replaced the human hand as the striking surface. The game took on characteristics we now associate with tennis: scoring systems and playing within prescribed boundaries.
In 1874 Major Walter Clopton Wingfield patented a game he called “Sphairistike” (Greek for “skill in playing ball”). It was played on an hour-glass shaped court with rackets and a light rubber ball filled with feathers. The earliest known tennis balls were made by N. Dunlop in Belfast Ireland around 1890. His ball was made of black rubber and filled with illuminating gas so it could be seen at night.
The Physics Of The Tennis Ball
A tennis ball has a diameter of about 2.7 inches (6.86 centimeters). To find the surface area, we need to know the radius of the ball, which is half the diameter. That means the radius of a tennis ball is 1.35 inches (3.43 cm).
Now that we know the radius, we can use the formula for the surface area of a sphere, which is 4 times pi times r squared. So in this case, we would have: 4 * 3.14 * (1.35)^2 = 11.68 square inches (75.92 square cm).
The Surface Area Of A Tennis Ball
The surface area of a tennis ball is approximately 4.7 square inches. This is based on the dimensions of a regulation tennis ball, which is 2.625 inches in diameter. To calculate the surface area, you need to know the circumference of the ball (C = 2πr) and then multiply that by the radius (r).
Conclusion
The surface area of a tennis ball is dimpled and therefore difficult to calculate without taking the dimples into account. However, a rough estimate of the surface area of a tennis ball can be made by considering it to be a perfect sphere with a radius of 2.54 centimeters. This would give the tennis ball a surface area of 33.5 square centimeters.
