The formula to find the surface area of a sphere is: [tex]A=4 \pi r^2[/tex] Let's plug in 7 for [tex]r[/tex]. [tex]A=4 \pi *7^2[/tex] The area would be: [tex]A=615.75[/tex]
The answer is just an approximation due to the fact that we are using [tex] \pi [/tex] Let me know if you have any questions! Thanks! -TetraFish
