Question

this person just posted a question "And ive been tryna work it out ohhhhh" phych seriously tho rlly i even need help tryna figure it out ..........The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount by pi and then multiply that by 4. This is written algebraically as S=4πr2, where S is the surface area, r is the radius, and the value of π is 3.14. Rewrite the equation to solve for the radius of the sphere if you know the sphere’s surface area. Then estimate the radius of a sphere given a surface area of 500 meters2.

Answer 1

and who ever answers this please show me the steps to show me were i went wrong

Answer 2

solve for r
\[4 \pi r^{2} = S\]
\[r^2 = \frac{S}{4\pi}\]
\[r = \sqrt{\frac{S}{4\pi}} = \frac{\sqrt{S}}{2 \sqrt{\pi}}\]
