jawaban klilinng kliling 1/2 lingkran K1.2 = 1/2 x phi x r = 1/2 x 22/7 x 7 = 11 k1/4 = 1/4 x 22/7 x7 = 1/2 x 11 = 5,5 kliling arsir = 29 + 14 + 22 + 7 + 5,5 + 11 = 88,5cm
= 2 × (36cm + 14cm) =
= 2 × 50cm = 100cm
Luas = (22cm + 14cm) × 14cm =
= 36cm × 14cm = 504cm
Semoga membantu :)
= ( 22 + 14 ) x 14
= 36 x 14
= 504
luas 1/2 lingkaran
L1/2 = 1/2 x phi x r²
= 1/2 x 22/7 x 7 x 7
= 11 x 7
= 77
luas 1/4 = 1/4 x 22/7 x 7 x7
= 1/2 x 11 x 7
= 38,5
luas arsir = 504 - 77 - 38,5
= 388,5 cm ²
jawaban klilinng
kliling 1/2 lingkran
K1.2 = 1/2 x phi x r
= 1/2 x 22/7 x 7
= 11
k1/4 = 1/4 x 22/7 x7
= 1/2 x 11
= 5,5
kliling arsir = 29 + 14 + 22 + 7 + 5,5 + 11
= 88,5cm
