Luas Lingkaran = phi x r². 2464 = 22/7 x r² 2464 x 7 = 22 r² 17248/22 = r² 784 = r² r = √784 r = 28 cm Maka : Keliling lingkran = 2 x phi x r = 2 X 22/7 X 28 = 2 X 22 X 4 = 176 cm .
2464 = phi . r kuadrat
2464 . 7/22 = r kuadrat
112.7 = r kuadrat
akar 784 = r
r = 28 cm
k = 2 phi r
= 22/7. 2 . 28
= 176 cm
2464 = 22/7 x r²
2464 x 7 = 22 r²
17248/22 = r²
784 = r²
r = √784
r = 28 cm
Maka :
Keliling lingkran = 2 x phi x r
= 2 X 22/7 X 28
= 2 X 22 X 4
= 176 cm .
