no 14 tolong di bantu ya terima kasih

Bangun Datar

JL^2 = JM^2 + LM^2
JL^2 = 16^2 + 30^2
JL^2 = 256 + 900
JL^2 = 1156
JL = √1156
JL = 34 cm

JL = d
r = 34/2
r = 17 cm

L lingkaran = π r r
= π x 17 x 17
= 289π cm^2

L persegi panjang = p x l
= LM x JM
= 30 x 16
= 480 cm^2

L arsiran = L lingkaran - L persegi panjang
= 289π - 480 cm^2 (D).

*semoga membantu. sukses selalu ^_^
