Jawab:
616m²
Penjelasan dengan langkah-langkah:
Diketahui :
Keliling = 88m
88m = π × d
88m = 22/7 × d
Dicari :
d = 7/22 × 88
d = 28m
r = ½d
r = ½ × 28
r = 14m
Luas = π × r × r
Luas = 22/7 × 14 × 14
Luas = 616m²
Jadi, luas taman tersebut adalah 616m²
Semoga Bermanfaat^^
k = 2 π r / π d
l = π r²
k = 88 m
r = ?
88 = π d
r = k ÷ π
r = 88 ÷ 22/7
r = 88 x 7/22
r = 4 x 7
d = 28
r = d x ½
r = 28 x ½
r = 14
l = 22/7 x 14²
l = 22/7 x 196
l = 22 x 28
l = 616 cm²
