Question

Find the surface area of the sphere with the given dimension. Leave your answer in terms of pi.
1. Radius of 60m?
2. Diameter of 14cm?

Answer 1

The surface area of a sphere is given by
\[S.A.=4 \pi r^2\]

Answer 2

Thats the equation for 1. For 2., since you have diameter you must use:\[\pi d ^{2}\]

Answer 3

Hi @Emily778 It looks like you posted your question in the wrong section. Instead of putting your question in the Mathematics Section, you placed it in the Physics Section. Next time just make sure you placed a specific question in the right section. Thanks :)
