Heya!!!
Step-by-step explanation:
Here's what you want :)
Diameter of the
semicircle ( d ) = 5.6cm
D = 2r
or r = 2.8 cm
1 ) perimeter of the semicircle
= πr + 2r
= 22r/7 + 2r
= 22/7r + 5.6
= 22/7 x 2.8 + 5.6
= 8.79+ 5.6
= 14.39 cm
2 ) area of the semicircle
= π r²/2
= ( 22 × 2.8 × 2.8 )/ ( 7 × 2 )
= 172.48/ 14
= 12.32 square cm
