Surface area of a sphere = 4 x (pi) x (radius)2

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!

Assuming the moon to be a sphere, the formula to find its surface area is 4/3*pi*r^3 where r is the radius of the moon.

Use this formula (Ï€ = Pi): Surface area = 4Ï€r2

Surface area of a sphere = 4*pi*radius2

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.

To find the surface area of a sphere, the formula is: 4pi*r2So plug in numbers: 4pi(4)24pi(16)=64pi

Surface area of a sphere = 4*pi*radius2

Surface area of a sphere = 4*pi*radius squared

The formula for the surface area of a sphere is 4 (pi) r2For a radius of 5 in, the surface area is4 (3.1416) (5)2 = 4 (3.1416)(25) = about 314.16 square inches

Yes. Second contribution: Surface area of sphere = XXXVI = 36 square inches. When all the working out is done, which the previous contributor has failed to do, the answer is: Volume of the sphere = 20.311 cubic inches correct to three decimal places. This was achieved by rearranging the formula (4*pi*r2) for finding the surface area of the sphere in order to find its radius. The radius was then used in the formula (4/3*pi*r3) for finding the volume of the sphere.

The surface area is 1,385.4 cm2
