1. 22/7 × 7 × 7 = 154

2. 22/7 × 17,5 × 17,5 =962,5

3. ¼ × 22/7 × 7 × 7 = 38,5

4. 22/7 × 7 × 7 = 154

1. luas = fi x jari jari
=22/7 x 7
=22

2.luas= fi x jari jari x jari jari
= 3,14 x 17,5 x 17,5
= 961,625

3. luas = fi x jari jari x jari jari : 1/4
= 22/7 x 7 x 7 : 1/4
= 154 : 4
= 38.5

4.luas = fi x jari jari x jari jari : 2 x 3
=22/7 x 7 x 7 : 2 x 3
=154 : 2 x 3
=77 x 3
= 231
