Hitunglah luas lingkaran dengan ketentuan sebagai berikut: A.r=30 cm B.r=15 dm C.r=1,4 cm D.d=30

A. L = phi(r^2) = 3,14 (30^2) = 2.826 cm^2
b. L = phi(r^2) = 3,14 ( 15^2) = 706,5 cm^2
c.L = phi(r^2) = 3,14 (1,4^2) = 6,1554 cm^2
d. L = phi(r^2) = 3,14 ( 15^2) = 706,5 m^2
e. L = phi(r^2) = 3,14 ( 20^2) = 1256 m^2
f. L = phi(r^2) = 3,14 (28^2) = 2.461,76 mm^2
