Surface area (square units)= 4 * pi * radius * radius
Volume (cubic units) = 4/3 * pi * radius * radius * radius
note:
pi = 3.1415926536 (approx)
Divide the diameter by 2 to get the radius. Then use the standard formula for the volume of a sphere.
If the radius is known, use this formula: V = 4/3(PI*r3)
Either use trial and error, or the quadratic formula, solving the following for x: x(x+1)=182Either use trial and error, or the quadratic formula, solving the following for x: x(x+1)=182Either use trial and error, or the quadratic formula, solving the following for x: x(x+1)=182Either use trial and error, or the quadratic formula, solving the following for x: x(x+1)=182
To do this question, we have to ask ourself, what formula do you use to find the surface area of a sphere. The answer should be known to you, but it is 4πr2. Since we know how to find the surface area for a full sphere, then finding the surface for a half sphere is just half the job. You use the formula for the full sphere 4πr2, and divide it by 2... so (4πr2) / 2 . Voila!
The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2. "r" is the radius; if you find the diameter of Earth somewhere, divide it by 2 to get the radius.The Earth is close enough to a sphere, so you can use the formula for a sphere: 4 x pi x r2.

Use the formula for volume to solve for the radius of the sphere and then plug that radius into the formula for the surface area of a sphere.
Divide the diameter by 2 to get the radius. Then use the standard formula for the volume of a sphere.
you use the quadratic formula in math when the quadratic equation you are solving cannot be factored.
If the radius is known, use this formula: V = 4/3(PI*r3)
Formula for calculating the area of sphere is : 4 * pi * r * r

use the formula 4/3*π*radius3 to find the volume of a sphere.
Distance divided by time Hope this helps!
If that's the radius, use the standard formula for the volume of a sphere.If that's the diameter, divide it by 2 to get the radius; then you can use the standard formula for the volume of a sphere.
First divide the diameter by 2 to give the radius and use the formula:- Surface area of a sphere = 4*pi*radius2 measured in square units
