Jawaban:

$a). : t = sqrt{ {10}^{2} - {8}^{2} } \ t = sqrt{100 - 64} \ t = sqrt{36} = 6 \ \ frac{1}{3} times 3.14 times 8 times 8 times 6 = 401.92 \ \$

$b). : r = sqrt{ {17}^{2} - {15}^{2} } \ r = sqrt{289 - 225} \ r = sqrt{64} = 8 \ \ frac{1}{3} times 3.14 times 8 times 8 times 15 = 1004.8 \ \$

$c). : frac{1}{3} times 3.14 times 2 times 2 times 24 = 100.48 \ \ d). : r = 40 div 2 = 20 \ \ frac{1}{3} times 3.14 times 20 times 20 times 21 = 8.792 \ \$

$e). : r = 32 div 2 = 16 \ \ frac{1}{3} times 3.14 times 16 times 16 times 30 = 8038.4 \ \$

$f). : t = sqrt{ {5}^{2} - {3}^{2} } \ t = sqrt{25 - 9} \ t = sqrt{16} = 4 \ \ frac{1}{3} times 3.14 times 3 times 3 times 4 = 37.68$
