Es krim berbentuk kerucut garis tengah alasnya 7 cm tingginya 9 cm, berapa cm volume es krim tersebut?
![]()
r = 7 ÷ 2 = 3,5 cm
- Volume
[tex] \tt = \frac{1}{3} \pi {r}^{2} t[/tex]
[tex] \tt = \frac{1}{3} \times \frac{22}{7} \times {3,5}^{2} \times 9[/tex]
[tex] \tt = \frac{22}{21} \times 12,25 \times 9[/tex]
[tex] \tt = \frac{2.425,5}{21} [/tex]
= 115,5 cm³

Jawab:
Penjelasan dengan langkah-langkah:
diameter = 7 cm
Jari-jari = 7/2
Tinggi = 9 cm
Volume = ⅓ x (22/7) x (7/2) x (7/2) x 9
Volume = ⅓ x 11 x (7/2) x 9
Volume = 115.5 cm³
