Matematika Hitunglah olume tabung berikut a) r- 3,5 cm dan t 70 cm b)r 8,5 cm dan t 21cm c)r4,5 cm t= 30 cm​

Hitunglah olume tabung berikut a) r- 3,5 cm dan t 70 cm b)r 8,5 cm dan t 21cm c)r4,5 cm t= 30 cm​

Jawaban:

v tabung =πr²t

a. 22/7(3,5)(3,5)(70)

maka 22(3,5)(35)

=2695 cm³

b.22/7(8,5)(8,5)(21)

maka 66(8,5)(8,5)

=4768,5 cm³

c. 22/7(4,5)(4,5)(30)

maka 22/7(45)(4,5)(3)

=990/7(13,5)

=1907,5 cm³
