Question

Find the surface area in square meters of a sphere with the diameter of 34 meters

Answer 1

Use the formula for the susface area of a sphere with radius r

`A=4\cdot\pi\cdot r^2`

remember that the radius is

`r=(D)/(2)`

find the radius

`r=(34)/(2)=17m`

replace in the formula for the surface area

`\begin{gathered} A=4\cdot\pi\cdot(17)^2 \\ A\approx3631.68 \end{gathered}`
