1. Tentukan keliling diameter lingkaran yang kelilingnya sebagai berikut! a. 314 cm b. 1.400 cm c. 200 cm Tolong dijawab ya yang tau soalnya bsk dikumpulin! TOLONG YA.......
a. 314 = 2(3,14)r r = 314/6,28 r = 50 => d = 100 cm b. 1400 = 2.3,14r r = 1400/6.28 r = 222.93 => 445.86 cm c. 200 = 2.3,14r r = 200/6.28 r = 31.85 => d = 63.69 cm
a. 314 = 2(3,14)r
r = 314/6,28
r = 50 => d = 100 cm
b. 1400 = 2.3,14r
r = 1400/6.28
r = 222.93 => 445.86 cm
c. 200 = 2.3,14r
r = 200/6.28
r = 31.85 => d = 63.69 cm
