17. L1= 1/2 x 3,14 x 20 x 20 = 1/2 x 314 x 2 x 2 = 628 L2= 1/2 x 3,14 x 10 x 10 = 1/2 x 314 x 1 x 1 = 157 L1 + L2= 628 + 157 = 785 A. 16. r= 1,5:2=0,75 L= 3,14 x 0,75 x 0, 75 =176,625 A. maaf klu salah
= 1/2 x 314 x 2 x 2
= 628
L2= 1/2 x 3,14 x 10 x 10
= 1/2 x 314 x 1 x 1
= 157
L1 + L2= 628 + 157
= 785 A.
16. r= 1,5:2=0,75
L= 3,14 x 0,75 x 0, 75
=176,625 A.
maaf klu salah
