Question

Tolong donggggg kalau hari senin mau dikumpulinnnnn
sama cara mencarinya yaaa ;-) :-)

Answer 1

Persegi  L= pxl = 24 x 12 = 288
tapesium  L= 1/2 (s1+s3) x t = 1/2 (24+6)x 10 = 150
segitiga  L = 1/2 ( ax t) = 1/2 ( 12 x 8 ) = 1/2 x 96 = 48


L lingkaran = /phi x r^2 = 3,14 x 24^2 = 3.14 x 576 = 1808....
keliling lingkaran = /phi x d = 3.14 x 48 =150,72

Answer 2

L pp = 24 x 12 =                                288 cm2
L trp = 1/2 x 10 x (24+6) = 5 x 30 = 150 cm2
L Δ = 1/2 x 8 x 12 =                              48 cm2
                                                         ----------------- +
L seluruhnya  =                                 486 cm2

L lingkaran = 24 x 24 x 3,14 = 1808,64 cm2
K                  = 2 x 24 x 3,14 = 150,72 cm

L prsegi = 36 x 36 =1296 cm2
K= 4 x 36 = 144 cm
L lingkaran = 18 x 18 x 3,14 = 1017,36 cm2
K = 36 x 3,14 = 113,04 cm
