$3.14\times 20\times 4+3.14\times {10}^{2}\times 2$
$=3.14\times 20\times 4+3.14\times 100\times 2$
$=62.8\times 4+314\times 2$
$=251.2+628$
$=879.2\left ( {{cm}^{2}} \right )$
$3.14\times {10}^{2}\times 4$
$=3.14\times 100\times 4$
$=314\times 4$
$=1256\left ( {{cm}^{3}} \right )$
$4\div 2=2\left ( {cm} \right )$
$3.14\times 4\times 10+3.14\times {2}^{2}\times 2$
$=3.14\times 4\times 10+3.14\times 4\times 2$
$=12.56\times 10+12.56\times 2$
$=125.6+25.12$
$=150.72\left ( {{cm}^{2}} \right )$
$3.14\times {2}^{2}\times 10$
$=3.14\times 4\times 10$
$=12.56\times 10$
$=125.6\left ( {{cm}^{3}} \right )$
圓錐：
$2\times 2=4\left ( {cm} \right )$
$\dfrac {1} {3}\times 0.9\times 3.14\times {2}^{2}$
$=\dfrac {1} {3}\times 0.9\times 3.14\times 4$
$=0.3\times 3.14\times 4$
$=0.942\times 4$
$=3.768\left ( {{cm}^{3}} \right )$
$30\div 2=15\left ( {cm} \right )$
$\dfrac {1} {3}\times {15}^{2}\times 3.14\times 5$
$=\dfrac {1} {3}\times 225\times 3.14\times 5$
$=75\times 3.14\times 5$
$=235.5\times 5$
$=1177.5\left ( {{cm}^{3}} \right )$
故答案為：
| 名稱 | 底面半徑/cm | 底面直徑/cm | 高/cm | 表面積/cm2 | 體積/cm3 |
| 圓柱 | 10 | 20 | 4 | 879.2 | 1256 |
| 2 | 4 | 10 | 150.72 | 125.6 |
| 圓錐 | 2 | 4 | 0.9 | —— | 3.768 |
| 15 | 30 | 5 | —— | 1177.5 |
