Answer:
Draw the line segment AB = 7 cm.
Draw ray BX making an acute ∠ABX.
Along BX. mark off five points B1, B2, B3, B4 and B5. Join B2 to A.
Through B5 draw B5P || B2A, intersecting BA produced at P.
The point P so obtained is the required point which divides AB externally in the ratio 3:5.
Answer:452.39 Edit: If not try 452.16 (Im not the best at math sorry)
Step-by-step explanation: A= 
x
Divide 24 by 2 to get the radius. Im not sure.
You should subtract 1.03 - 0.6 to get your answer(i really hope so cause i dont like giving wrong answers) 0.43(i was just gonna say "0.43" but no less than 20 characters):)
example:all students are 39
