tolong Jawab diatas ini yq!dan pake carakeliling dan luasnya

Jawabanya ;

Keliling 1/2 lingkaran
= 1/2 × phi × d
= 1/2 × 3,14 × 60 cm
= 1/2 × 188,4 cm
= 94,2 cm

Luas 1/2 lingkaran
= 1/2 × phi × r^2
= 1/2 × 3,14 × 30 cm × 30 cm
= 1/2 × 2826 cm
= 1413 cm^2

Selamat Belajar :)

L= Diameter 60= r=30
=1/2×3,14×30×30=1/2×3,14×900=3,14×450=1,413

K= Diameter=60=r=30
=1/2×2×3,14×30=1/2×6,28×30=1/2×188,4=94.2

Maaf Kalo Salah
Kasih Terimakasihnya :v
