tolong ya kak pliss

keliling lingkaran:110cm
nilai π:22/7
panjang diameter:-
panjang jari jari:-
tolong dijawab ya kak​

Enjoyyyy (^^)

• diameter

K = πd

110 cm = 22/7 × d

d = 110 ÷ 22/7

d = 110 × 7/22

d = 770/22

d = 35 cm

• jari-jari

Cara 1:

r = d/2

r = 35/2

r = 17,5 cm

Cara 2:

K = 2πr

110 cm = 2 × 22/7 × r

110 cm = 44/7 × r

r = 110 ÷ 44/7

r = 110 × 7/44

r = 770/44

r = 17,5 cm

Ket: r = jari-jari

d = diameter

K = keliling
