Jawaban:
1. dik: d = 14 cm
K = phix d = 22/7 x 14
= 44 cm3
L=phixrxr = 22/7 x 7 x 7
= 154 cm2
2. Diameter lingkaran = 80 cm
π = 3,14
Ditanya: Luas lingkaran...?
Jawab:
r=d: 2=80:2= 40 cm
L = mxrxr
L = 3,14 x 40 x 40
L = 5.024 cm²
4. Diameter = 150 cm
maka r=d:2
r-150 cm:2
r-75 cm
k=xd
= 3,14x150 cm
=471 cm
L=nxrxr
= 3,14x75 cmx75 cm
= 3,14x5.625 cm
-17.662,5 cm²
Penjelasan dengan langkah-langkah:
semoga membantu. maaf nomor 3 gak tau
