Surface area of a sphere = 4*pi*radius2
Surface area of a ball or sphere = 4*pi*radius2
Surface area of the ball = 4*pi*342 = 4624*pi square mm
Surface area = 4*pi*162 = 3216.990877 or about 3217 cubic cm
2800 square inches
Surface area of a ball or a sphere = 4*pi*radius squared
Surface area = 4*pi*radius2
Surface area of a sphere = 4*pi*radius2
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.
Surface area of a ball or sphere = 4*pi*radius2
Surface area of the ball = 4*pi*342 = 4624*pi square mm
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.
Surface area of ball: 4*pi*1^2 = 4*pi square feet
Surface area = 4*pi*162 = 3216.990877 or about 3217 cubic cm
2800 square inches
