Question

No 29&30 tolong di jawab ya, please

Answer 1

29. dik = t= 24      r = 7
dit= volume
jawab= volume= v kerucut + v 1/2 bola
= 1/3 x pi. r^2 x t + 4/3 x 1/2 x pi. r^3
= 1/3 x 22/7 x 7 x 7 + 4/3 x 1/2 x 22/7 x 7 x 7
= 1232 + 718,6
= 3182,66667

30. v= 1232
r= 7

v=1/3 x22/7 x 7 x 7 x t
1232 = 154/3 t
t = 24
