tlong jwb soal ini bsrta jalan ny

1. B. 10.5
Kel =Π.d
66 = 22/7×d
D=21 r=10.5

3. 22/7 x 42 = 132
132:4 = 33 pohon

4. ¼ Πd
¼ x 22/7 x 14 = 11 cm

1.) Kel =Π.d
66 = 22/7×d
d=21
r= 1/2 ×d = 1/2 × 21 = 10.5cm (B)

2.) keliling = 628/500 = 1,256m^2
d = keliling / phi
d = 1,256/3,14
d = 0,4m × 100 = 40cm (d)

3.) 22/7 x 42 = 132
132:4 = 33 pohon (b)

4.) Keliling = (1/4 × 2 × 22/7 × 7)
Keliling = 11cm (a)

Kalau boleh jadikan jawaban terbaik yah.
