dijwb yaa...fast klo bisaa. w kasih poin byk

1). AB dan CE

2). r=10x3=30
L=π r²
=3,14x30²
=3,14x900
=2.826 cm²

3). keliling=2 x π r
=2x3,14x25
=6,28x25=157
panjang lintasan=157x45=7.065 cm =70,65 m

SEMOGA MEMBANTU YAAAA.......

1. AB, CE
2. luas = 3,14 × 900 = 2826
3. panjang lintasan = 2 × 3,14 × 25 × 45 = 70,65 meter
