1. V = Luas alas x tinggi Luas alas = a x t /2 L alas = 15 x 36 /2 L alas = 270 V = 270 x 10 V = 2700cm³
2. V = Luas alas x tinggi Luas alas = 22/7 x r² r = diameter /2 r = 28/2 r = 14 Luas alas = 22/7 x 14² Luas alas = 616 V = 616 x 33 V = 20328cm³ 3. V = Luas alas x tinggi V = 180 x 35 V = 6300cm³
4. V = Luas alas x tinggi 1848 = 22/7 x r² x 12 1848/12 = 22/7 x r² 154 = 22/7 x r² 153 x 7/22 = r² 49 = r² r = √49 r = 7cm 5. V = Luas alas x tinggi Luas alas = 1/2 x a x t Luas alas = 1/2 x 12 x 12 Luas alas = 6 x 12 Luas alas = 72 V = 72 x tinggi 2160 = 72t t = 2160/72 t = 30
Luas alas = a x t /2
L alas = 15 x 36 /2
L alas = 270
V = 270 x 10
V = 2700cm³
2. V = Luas alas x tinggi
Luas alas = 22/7 x r²
r = diameter /2
r = 28/2
r = 14
Luas alas = 22/7 x 14²
Luas alas = 616
V = 616 x 33
V = 20328cm³
3. V = Luas alas x tinggi
V = 180 x 35
V = 6300cm³
4. V = Luas alas x tinggi
1848 = 22/7 x r² x 12
1848/12 = 22/7 x r²
154 = 22/7 x r²
153 x 7/22 = r²
49 = r²
r = √49
r = 7cm
5. V = Luas alas x tinggi
Luas alas = 1/2 x a x t
Luas alas = 1/2 x 12 x 12
Luas alas = 6 x 12
Luas alas = 72
V = 72 x tinggi
2160 = 72t
t = 2160/72
t = 30
