r 2 = L / 22/7 = 616 x 7/22 = 196 r = 14 cm jadi d= 14 x 2 = 28 cm

L = r^2 616 = 22/7 . r^2 r^2 = 616 x 7/22 r^2 = 28 x 7 r^2 = 196 r = r = 14 cm panjang diameter yaitu d = 2 x r = 2 x 14 = 28 cm jadi panjang diameternya adalah 28 cm.
ditanya diameter
r 2 = L / 22/7
= 616 x 7/22
= 196
r = 14 cm
jadi d= 14 x 2 = 28 cm
616 = 22/7 . r^2
r^2 = 616 x 7/22
r^2 = 28 x 7
r^2 = 196
r =
r = 14 cm
panjang diameter yaitu
d = 2 x r = 2 x 14 = 28 cm
jadi panjang diameternya adalah 28 cm.
