c.1.644,67cm³
d.1.645,67cm³

tolong dijawab ya

Volume bingung diatas adalah….

Jawaban:

$A.) 1.642,67 : {cm}^{3}$

Penjelasan dengan langkah-langkah:

$v : tabung : = pi times {r}^{2} times t \ = frac{22}{7} times {7}^{2} times 9 \ = 22 times 7 times 9 \ = 1.386 : {cm}^{3}$

$v : kerucut = frac{1}{3} times pi times {r}^{2} times t \ = frac{1}{3} times frac{22}{7} times {7}^{2} times 5 \ = frac{1}{3} times22 times 7 times 5 \ = 256,67 : {cm}^{3}$

$v : total = 1.386 + 256,67 \ = 1.642,67 : {cm}^{3}$

Penjelasan dengan langkah-langkah:

V Tabung : π × r × r × t

= 22/7 × 7 × 7 × 9

= 22 × 1 × 7 × 9

= 22 × 7 × 9

= 154 × 9

= 1.386

V Kerucut : π × r × r × t

= 1/3 × 22/7 × 7 × 7 × 5

= 1/3 × 22 × 1 × 7 × 5

= 22/3 × 1 × 7 × 5

= 22/3 × 7 × 5

= 154/3 × 5

= 770/3

= 256,7

Jumlah V = 1.386 + 256,7 = a.1.642,67cm³
