Question

Tolong jawab ya kaa,,, yg bisa aja

Answer 1

6. L=1/4 x phi x r x r
=1/4 x 3,14 x 10 x 10
=1/4 x 314
=314:4
=78,5 cm2

7. K= 2 x phi x r
=2 x 3,14 x 10
=2 x 31,4
=62,8 cm

8. V= La x t
560=La x 8
La= 560:8
La= 70 cm

9. K=4 x s
60=4 x s
s= 60:4
s=15 cm
L=s x s
= 15 x 15
= 225 cm2

10. L= d1 x d2 : 2
=64 x 81 : 2
=5184:2
=2592 cm2

semoga membantu
