Luas lingkaran yg kelilingnya 176cm dg phi=22per7 adalah.....
FaridatulUmmi99
Keliling = 2 π r 176 = 2x 22 x r 7 r = 28 luas = 22 x 28 x28 7 = 2464

176 = 2 x 22/7 x r <=> 176 = 44/7 x r <=> r = 7 x 176/44 = 28 cm maka, luas lingkaran = π r² = 22/7 x 28 x 28 = 2464 cm² {semoga membantu :D }
176 = 2x 22 x r
7
r = 28
luas = 22 x 28 x28
7
= 2464
maka, luas lingkaran = π r² = 22/7 x 28 x 28 = 2464 cm² {semoga membantu :D }
