Answer:

x = 12√2

Step-by-step explanation:

This is a right triangle, which makes things easier. Both legs have length 12.

Using the Pythagorean Theorem, we get x^2 = 12^2 + 12^2, or 2(144).

Solving for x, we get x = 12√2.

Consider two parallel line segments.

Kaylis [27]

Answer:

Part A: -3/7

Part B: y = -2

Step-by-step explanation:

Parallel lines have the same slope. Find the slope of CD. Then substitute it to find the value needed for AB.

The slope formula is

$m = \frac{y_2-y_1}{x_2-x_1} = \frac{4-1}{-5-2} = \frac{3}{-7}$

Use the same formula and solve for y.

$m = \frac{y_2-y_1}{x_2-x_1}\\\\-\frac{3}{7}= \frac{y--5}{-6-1} \\\\\frac{3}{-7} =\frac{y+5}{-7}\\\\3 = y+5\\3-5 = y\\-2 = y$

Use the net below to determine the surface area of the cylinder. (Use 3.14 for Tr.)

baherus [9]

Option D:

Surface area of the cylinder = 753.6 cm²

Solution:

<u>To find the surface area of the cylinder:</u>

Given data:

Radius of the cylinder = 6 cm

Height of the cylinder = 14 cm

The value of π = 3.14

Surface area of the cylinder = $2 \pi r^{2}+2 \pi r h$

$=2\times 3.14\times6^2+2\times3.14\times 6 \times14$

= 226.08 + 527.52

= 753.6 cm²

Surface area of the cylinder = 753.6 cm²

Option D is the correct answer.
