Apie chart shows the relative market share of cola products. the "slice" for pepsi-cola has a central angle of 90 degrees. what is its market share?

My answer to the problem is as follows:

Since there is 360 degrees in a circle so the fraction that Pepsi represents is
90/360

Therefore, the market share would be 90/360 or 1/4 or 0.25.

I hope my answer has come to your help. God bless and have a nice day ahead!
