X + 14 + x + 14 = 17 + x + 7
2x + 28 = 24 + x
2x - x = 24 - 28
x = -4

DF = x + 14
= (-4) + 14
= 10

HELP ME PLZZZZ!!!!!!!!!!!!!!!!!!

the radius of the distance between the middle point of the circle and the outside, we have the diameter which is 6 so the radius will be 3

slant height is

$\sqrt{r^2+h^2}$

h is 4.7 and r is 3

$\sqrt{3^2+4.71^2} \\5.58427$

slant height is 5.58427

lateral surface area

$\pi r\sqrt{h^2+r^2}$

$\pi (3)\sqrt{4.71^2+3^2} \\52.63053$

lateral surface area is 52.63053

total surface area

$\pi r(r+\sqrt{h^2+r^2})$

$\pi 3(3+\sqrt{4.71^2+3^2})$

$80.90486$

total surface area is 80.90486
