Figure 1: Part of the surface of a sphere. For this example we’ll let the radius equal a, so that we can see how the surface area depends on the radius. Then: y = p a2 x2 y0 = x p a2 x2 ds = r 1 + x2 a2 x2 dx = r a2 x2 + x2 a2 x2 dx = r a2 a2 x2 dx The formula for the surface area indicated in Figure 1 is: Area = Z x 2 x 1 2ˇyds = Z x 2 x 1 ...

Free surface area of a sphere GCSE maths revision guide, including step by step examples, exam questions and free worksheet.
We explain how to find the surface area of a sphere and provide a quick calculator to work it out for you, step-by-step. There is also a separate calculator which will find the radius and diameter of a sphere, if you already know the surface area.
Here you will learn about the surface area of a sphere, including how to calculate the surface area of a sphere given its radius and the surface area of a hemisphere. Students will first learn about the surface area of a sphere as a part of geometry in 8 th grade.
Example. Find the surface area of a sphere with a diameter of \hspace {0.2em} 28 28 inches. Solution. The surface area of a sphere is given by - A = 4 \pi r^2 A = 4πr2. But the question doesn't give us the radius \hspace {0.2em} (r) (r). Instead, it tells us the diameter is \hspace {0.2em} 28 \hspace {0.2em} 28 inches.
In this example we will complete the calculation of the area of a surface of rotation. If we’re going to go to the effort to complete the integral, the answer
