27.D. 1.256

28.A. 42 cm²

29.....

30.B. 308 cm²

Penjelasan dengan langkah-langkah:

27. d=40cm

r=40 : 2

=20cm

L= π x r²

= 3,14 x 20 x 20

= 3,14 x 400

= 1.256 cm ²

28.d=14cm

r=14 : 2

=7cm

L= π x r²

= 22/7 x 7 x 7

= 154 cm²

L= s x s

= 14 x 14

= 196cm²

196

154 -

042cm²

30.r=14cm

L1/2= π x r²/2

= 22/7 x 14 x 14

= 616/2

= 308cm²
