7.85+5+5=17.85 in

Answer 2

`answer = 17.85 {inches} \\ solution \\ radius = 5 \: inches \\ perimeter \: of \: quarter \: circle \\ = (2\pi \: r)/(4) + 2r \\ = (2 * 3.14 * 5)/(4) + 2 * 5\\ = (31.4)/(4) + 10 \\ = (31.4 + 10 * 4)/(4) \\ = (31.4 + 40)/(4) \\ = (71.4)/(4) \\ = 17.85 \: {inches} \\ hope \: it \: helps`
