1: Isha has the bigger part (:3)
2: or Isha has the smaller part (2:)
1.
Isha = 3x = 600
solve for x:
x = 600/3 = 200
Then Roger has 2x = 2*200 = 400
600:400
6:4
3:2
the ratio complies, Isha has 600 and Roger 400
2.
Isha = 2x = 600
x = 300
Roger = 3x = 3*300 = 900
600:900
6:9
2:3
the ratio complies, Isha has 600 and Roger 900

Answer:
Using 3.14 for pi
835.24 cm^2
Using the pi button for pi
835.6636459 cm^2
Step-by-step explanation:
The surface area of a cylinder is given by
SA = 2 pi r^2 + 2 pi r h
= 2 * pi ( 7)^2 + 2 pi ( 7) * 12
= 98 pi + 168 pi
=266 pi
