Answer 2

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

Area of shaded portion = area of big semi circle - area of small semi circle

=7.8-1.52

=6.28 cm/m
