100 x pi m2

It is 314.159 or 100*pi square units.

First find the radius: 4*pi*r2 = 100*pi cm2 Divide both sides by 4*pi and then square root the answer: radius = 5 cm Volume = 4/3*pi*radius3 Volume = 523.5987756 or about 524 cm3

If you means surface area of a sphere, then use this formula: A = r^2 * pi * 4 where: A= surface area r=radius pi=~3.14159 e.g.: A = 5^2 * 3.14159 * 4 A = 25 * 3.14159 * 4 A = 100 * 3.14159 A = ~314.16 cm^2 If you actually mean volume of a sphere, then use this formula: V = r^3 * pi * (4/3) where: V= volume r=radius pi=~3.14159 e.g.: V = r^3 * pi * (4/3) V = 5^3 * 3.14159 * 4/3 V = 125 * 3.14159 * 4/3 V = ~523.6 cm^3

Surface area of the sphere: 4*3.14*radius2 = 314 square inches Divide both sides by 4*3.14 and then square root both sides to find the radius: Radius = 5 inches Circumference = 2*3.14*5 = 31.4 inches

There are two methods, you can decide which is easier for you to follow. 1. Calculate the value for surface area (4π(r^2)) or volume ((4/3)π(r^3)) depending on the problem you're working on, using the new value and the old values for the radius. Then, take the new radius (the triple-sized one) and subtract the previous value, and divide that number by the previous value to get the decimal. To make that into a percentage, multiply by 100. 2. Subtract the smaller radius by the larger one. Calculate the value for surface area/volume. That solution is the difference in surface area/volume due to the larger radius. Then, divide that number by the original surface area/volume (the solution of the original radius put through the equation) to get the decimal. Multiply by 100 to make a percentage.

If you means surface area of a sphere, then use this formula: A = r^2 * pi * 4 where: A= surface area r=radius pi=~3.14159 e.g.: A = 5^2 * 3.14159 * 4 A = 25 * 3.14159 * 4 A = 100 * 3.14159 A = ~314.16 cm^2 If you actually mean volume of a sphere, then use this formula: V = r^3 * pi * (4/3) where: V= volume r=radius pi=~3.14159 e.g.: V = r^3 * pi * (4/3) V = 5^3 * 3.14159 * 4/3 V = 125 * 3.14159 * 4/3 V = ~523.6 cm^3
