Question

Tolong!! buat besuk mohonpakek caranya

Answer 1

3. L =πr²
=π.(28/2)²
=π.14²
=22/7.14²
=616

4. L =πr²
=3,14.100
=314

5. L=πr²
=3,14.11²
=379,94

6. L=π.r²
1366=π.r²
r =√1366 : 3,14
=34,29

7. V = La.t
=1/2 . a.t.tprisma
=1/2. 7.24.48
=4032

8. V = La.t
=πr².t
=22/7 . 16 .16 . 56
=45056

Semoga membantu.......
