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
S.A. = 4 pi r^2 Substituting 314 = 43.14r^2 Algebraically rearrange 100/4] r^2 = 314 / (4 * 3.14) r = sqrt[314/(4*3.14)] r = sqrt[ 100/4] r = sqrt[25] r = 5 inches The circumference of a sphere is a circle. Hence C = 2 pi r C = 23.145 C = 10*3.14 C = 31.4 inches.

The formula for the surface area of a sphere is 4 (pi) r2For a radius of 10 cm, the surface area is4 (3.1416) (10)2 = 4 (3.1416)(100) = about 1256.64 cm2
100 x pi m2
The surface area of a sphere is 4 pi R2A = 4 pi (5)2 = 100 pi = 314.16 square meters (rounded)
It is 314.159 or 100*pi square units.
It is: 4*pi*52 = 314.159 square cm to three decimal places
The surface area is 314.16 units2
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
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.
