Question

!!!!!! URGENT PLS HELP ME ANSWER !!!!

Answer 1

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

Explanation:

1)

`A = \Pi ((D)/(2))^2 = 3.14 * ((26.4)/(2))^2 = 3.14 * 13.2^2 = 547.1136`

`C = \Pi D = 3.14 * 26.4 = 82.896`

2)

`A = \Pi r^2 = 3.14*(14.7)^2 = 678.5226`

`C = 2\Pi r = 14.7*2 * 3.14 = 92.316`

3)

`A = \Pi ((D)/(2))^2 = 3.14 * ((32.8)/(2))^2 = 3.14 * 16.4^2 = 844.5344`

`C = \Pi D = 3.14 * 32.8 = 102.992`

4)

`A = \Pi ((D)/(2))^2 = 3.14 * ((44.5)/(2))^2 = 3.14 * 22.25^2 = 1554.49625`

`C = \Pi D = 44.5*3.14 = 139.73`

5)

`A = \Pi r^2 = 3.14*22.3^2 = 1561.4906`

`C = 2\Pi r = 2 * 3.14 * 22.3 = 140.044`

6)

`A = \Pi r^2 = 3.14 * 17.8^2 = 994.8776`

`C = 2\Pi r = 2 * 3.14 * 17.8 = 111.784`
