Dik: r²= 14cm
Dit: K?
Jawab
K= 2πr
K= 2×22/7×14
K= 2×44
K= 88cm
Mohon maaf apabila ada kesalahan
Jawaban:
B. 44 cm
Penjelasan dengan langkah-langkah:
k = 1/2 x π x d (ada 1/2 karena 1/2 lingkaran)
= 1/2 x 22/7 x 28
=1/1 x 11/1 x 4/1
=1 x 11 x 4
=11x4
=44
keterangan
d = r x 2
= 14 x 2
= 28
maaf kalo salah
