Answer:
1) A = 547.1136, C = 82.896
2) A = 678.5226, C = 92.316
3) A = 844.5344, C = 102.992
4) A = 1554.49625, C = 139.73
5) A = 1561.4906, C = 140.044
6) A = 994.8776, C = 111.784
Step-by-step explanation:
1)
[tex]A = \Pi (\frac{D}{2})^2 = 3.14 * (\frac{26.4}{2})^2 = 3.14 * 13.2^2 = 547.1136[/tex]
[tex]C = \Pi D = 3.14 * 26.4 = 82.896[/tex]
2)
[tex]A = \Pi r^2 = 3.14*(14.7)^2 = 678.5226[/tex]
[tex]C = 2\Pi r = 14.7*2 * 3.14 = 92.316[/tex]
3)
[tex]A = \Pi (\frac{D}{2})^2 = 3.14 * (\frac{32.8}{2})^2 = 3.14 * 16.4^2 = 844.5344[/tex]
[tex]C = \Pi D = 3.14 * 32.8 = 102.992[/tex]
4)
[tex]A = \Pi (\frac{D}{2})^2 = 3.14 * (\frac{44.5}{2})^2 = 3.14 * 22.25^2 = 1554.49625[/tex]
[tex]C = \Pi D = 44.5*3.14 = 139.73[/tex]
5)
[tex]A = \Pi r^2 = 3.14*22.3^2 = 1561.4906[/tex]
[tex]C = 2\Pi r = 2 * 3.14 * 22.3 = 140.044[/tex]
6)
[tex]A = \Pi r^2 = 3.14 * 17.8^2 = 994.8776[/tex]
[tex]C = 2\Pi r = 2 * 3.14 * 17.8 = 111.784[/tex]
