Shooter

The shooter fired to a target from distance 11 m The individual concentric circle of targets have a radius increments 1 cm (25 points) by 1 point. Shot was shifted by 8'(angle degree minutes).

How many points should win his shot?

Result

n =  23

Solution:

r=11tan8=0.0256 m=2.56 cm n=252=23r = 11 \cdot \tan 8' = 0.0256 \ m = 2.56 \ cm \ \\ n = 25 - 2 = 23
