3/4 volume tabung d:7 , t:28

Diket :
D = 7, r = 3,5
t = 28
V = 3/4

Jawab :
V = π.r²t
V = 22/7.(3,5)².28
V = 22(4).(12,25)
V = 88 x 12,25
V = 1078

3/4V = ...
3/4(1078) = ...
3(369,5) = 808,5

Maaf jika ad kesalahan :)

Volume tabung =
[tex]\pi \: {r}^{2} t[/tex]
d = 7 → r = 3,5
t = 28

[tex] \frac{22}{7 } \times 3.5 \times 3.5 \times 28 = 1078[/tex]
Karena 3/4 volumenya, maka

3/4 × 1078 = 808,5
