Question

answer the following question​

Answer 1

Answer:

$25344 \: {cm}^{3}$

Step-by-step explanation:

$h = 56 \: cm \\ x = 20 \: cm \: \\ y = 16 \: cm \\ \\ volume = \pi( {x}^{2} - {y}^{2} )h \\ \frac{22}{7} \times ( {20}^{2} - {16}^{2} )h \\ \\ = \frac{22}{7} \times ( {400}^{} - {256}^{} ) \times 56 \\ \\ = \frac{22}{7} \times 144 \times 56 \\ \\ = 2 2\times 144 \times 8 \\ \\ = 176 \times 144 \\ \\ 25344 \: {cm}^{3} .$
