Q.
Volume kerucut dengan jari-jari 28cm dan tinggi 12cm?

V = 1/3 × π × r² × t

V = 1/3 × 22/7 × 14² × 12

V = 1/3 × 22/7 × 196 × 12

V = 1/3 × 616 × 12

V = 1/3 × 7.392

V = 2.464 cm³

$tt = 8.960 : cm³$

Penjelasan dengan langkah-langkah:

Volume kerucut

$tt = ⅓ × π × r² × t$

$tt = ⅓ × frac{22}{7} × 28² × 12$

$tt = 1 × frac{22}{7} × 784 × 4$

$tt = 1 × 22 × 112 × 4$

$tt = 22 × 448$

$tt = 8.960 : cm³$
