Question

the surface of a baseball is 177 cm^2. What is the diameter of the baseball

Answer 1

well the surface area of a sphere can be found using

\[SA = 4 \pi r^2\]

so substitute 177 and solve for r

\[177 = 4 \pi r^2\]

Answer 2

I'm not getting the answer

Answer 3

so what are you getting...?

Answer 4

14.01

Answer 5

To find 'r' of
\[SA = 4 \pi r^2\]
You rearrange the equation
\[r = \sqrt{\frac{ SA }{ 4 \pi }}\]
Then do what campbell_st said by substituting SA with 177

Answer 6

The amount you figure out here would be the radius which you would then double to get the diameter
