Since we know that the 38 is being bisected (which we can tell by the fact that the line hits it perpendicularly), we know that from the intersection to the edge of the circle is 19. From this we can create a right triangle in which the legs are 10 and 19 and the hypotenuse is a radius of the circle. Since x is also a radius of the circle, all we have to do is use that information to find the hypotenuse using the Pythagorean Theorem and we have x. 

Pythagorean Theorem
a^{2} + b^{2} = c^{2}
10^{2} + 19^{2} = x^{2}
100 + 361 = x^{2}
461 = x^{2}
x = \sqrt{461} or about 21.47

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

slant height is

\sqrt{r^2+h^2}

h is 4.7 and r is 3

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

<u>slant height is 5.58427</u>

lateral surface area

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

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

<u>lateral surface area is 52.63053</u>

total surface area

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

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

80.90486

<u>total surface area is 80.90486</u>

a construction crew Must build 4 miles of road in one week on Monday they build 1/2 mile of road in one week on Tuesday they bui
NNADVOKAT [17]
To solve this, you need to make the amount they built on Monday and the amount they built on Tuesday compatible with each other so you can add them together to subtract that amount from 4.

Start by multiplying 1/2 by 3, and 1/3 by 2.

This gives you 3/6 and 2/6. Now add them together:

3/6 + 2/6 = 5/6

Finally, subtract this amount from 4:

4 - 5/6 = 3 1/6 (19/6 works too)

Hope this helps! :)
