Find The Surface Area In Square Meters Of A Sphere With The Diameter Of 34 Meters class=

Sagot :

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

[tex]A=4\cdot\pi\cdot r^2[/tex]

remember that the radius is

[tex]r=\frac{D}{2}[/tex]

find the radius

[tex]r=\frac{34}{2}=17m[/tex]

replace in the formula for the surface area

[tex]\begin{gathered} A=4\cdot\pi\cdot(17)^2 \\ A\approx3631.68 \end{gathered}[/tex]
