Question

what is the approximate surface area of the sphere? C=37.68

Answer 1

\(\bf {\color{brown}{ c}}ircumference=2\pi r\qquad \{{\color{brown}{ c}}=37.68\qquad {\color{brown}{ 37.68}}=2\pi r\)

solve for "r", see what you get for the radius
and use that to find the area of the circle

Answer 2

How do you find the radius

Answer 3

does it matter that this is not a circle it is a sphere?

surface area of a sphere = 4 * pi* r^2

Answer 4

I actually found the answer but thank you!
