Answer:
Step-by-step explanation:r of big semi circle =5 cm/m
Area of semi circle =1/2 ×pie ×r²
Area of big semicircle = 1/2×3.14×5
=1/2×15.6
=7.8 m or cm ( because unit is not mentioned)
Area of small semi circle = 1/2×3.14×1
= 1.52
Area of shaded portion = area of big semi circle - area of small semi circle
=7.8-1.52
=6.28 cm/m
