Question

2. Find the surface area of the sphere below. Leave your answer in terms of . Type 'pi' to represent Pi

Answer 1

Given the surface area of the sphere

Formular

`\begin{gathered} \text{Surface Area = 4}\pi r^2 \\ S\mathrm{}A\text{ = 4 }\pi(2.5)^2 \\ S.A\text{ = 25 }\pi cm^2 \end{gathered}`

Hence the surface area of the sphere = 25 π cm²
