What is the surface area of the ball if it has a radius of 1 foot .?
Surface area of ball: 4*pi*1^2 = 4*pi square feet
What is the radius of a ball with surface area of 153.94?
Radius = square root of (153.94/4pi) = 3.5 to one decimal place
The circumference of a hollow ball is 19cmwhat is the surface area?
First find the radius by dividing 19 by 2*pi which is 3.023943919 cm Surface area of a sphere (the ball) = 4*pi*radius2 Surface area = 4*pi*3.0239439192 => 114.9098689 Surface area of the ball: 115 square centimeters correct to three significant figures.
Which has the greater surface to volume ratio a tennis ball or basketball explain your answer what could be done to increase the surface to volume ratio of both?
They are spheres. They cannot therefore have different geometrical properties. To alter surface to volume ratios you would need to alter the shape. The study of mathematical shapes is called topology.
How do you calculate the volume of a tennis ball?
To a first approximation, a tennis ball is a sphere. The volume of a sphere is V = 4/3 π r3, where r is the radius of the sphere. So measure the diameter of the tennis ball, divide by 2 to get the radius, and then apply the formula above. You could also measure the volume of a tennis ball by measuring the volume of water that it displaces.
How can you increase the surface to volume ratio of a basketball and a tennis ball?
The tennis ball. But do you know why? The anser to that is in the relationship between the fomula for a shere's volum and that of it's surface area. Area is a radius squared function whereas volume is a radius cubed function.
What is the surface area of a soft ball?
Surface area of a ball or a sphere = 4*pi*radius squared
What is the surface area of tennis ball?
Surface area of a sphere = 4*pi*radius2
What is surface in science?
Surface Area is the term used to describe the area of an object that is exposed. In other words, if you took a tennis ball, the outside of the ball is it's surface area. If you cut the tennis ball in half, the original outside part is still part of the surface area but now include the inside as well.
What is the surface area of a ball with a radius of 4 centimeters?
66.98 sqcm
A ball has a radius of 1 foot What is the surface area of the ball?
4 pie ft. 2
What surface area is larger baseball or soccer?
A soccer ball has a larger radius than a baseball, so it has more surface area.
What is the surface area of the ball if it has a radius of 1 foot .?
Surface area of ball: 4*pi*1^2 = 4*pi square feet
What is the radius of a ball with surface area of 153.94?
Radius = square root of (153.94/4pi) = 3.5 to one decimal place
What is the surface area of the ball that has a radius of 1 foot?
Surface area of a sphere = 4πr²A= 4(3.14159) X 1A= 12.56 ft²
How will increasing the diameter of the tennis ball slow a ball in the air?
the more surface area, the more friction, the more the drag
