Kak bantu jawab??plissssssss
PENYELESAIAN:
NOMOR 1
L = Π × R × R
L = 3,14 × 15 × 15
L = 706,5 DM²
NOMOR 2
L = Π × R × R
L = 22/7 × 56 × 56
L = 9856 CM²
NOMOR 3
L = 1/4 × Π × D × D
L = 1/4 × 22/7 × 35 × 35
L = 962,5 CM²
NOMOR 4
D = √22.176/11 × 14
D = √28244
D = 168 CM
NOMOR 5
R = √1256/3,14
R = √400
R = 20 CM
JAWABAN:
JADI, JAWABANNYA ADALAH:
- 706,5 DM²
- 9856 CM²
- 962,5 CM²
- 168 CM
- 20 CM
