Answer 1

→ 2(sisi 1 + sisi 2) + πd

→ 2(16 + 15) + 22/7 × 14 cm

→ 2(31) + 308/7 cm

Answer 2

Verified answer

Jawaban:

Diketahui :

r = 15 cm

d = 15 cm x 2 = 30 cm

Ditanyakan :

Keliling 3/4 lingkaran ?

Dijawab:

k = 3/4 × π x d + (2r)

= 3/4 x 3,14 x 30 cm + ((2) ( 15 ))

= 3/4 × 3,14 x 30 cm + 30

= 22,5 × 3,14 + 30

= 70,65 + 30 cm

= 100,65 cm
