Find the surface area of the cylinder and round to the nearest tenth. (It is recommended that you use the π button on your calcu
elena-s [515]

The surface area of the cylinder is 18.84 square feet

<h3>How to determine the surface area?</h3>

The given parameters are

Height, h = 2 ft

Diameter, d = 2 ft

The radius (r) is half of the diameter (d)

This is calculated as:

Radius = Diameter/2

So, we have:

r = d/2

Substitute 2 for d

r = 2/2

Evaluate the quotient i.e. divide 2 by 1

r = 1

The surface area is then calculated using the following formula

A = 2πr² + 2πrh

Substitute the given values in the above equation

So, we have:

A = 2 * 3.14 * 1^2 + 2 * 3.14 * 1 * 2

Evaluate the exponents

A = 2 * 3.14 * 1 + 2 * 3.14 * 1 * 2

Evaluate the products

A = 6.28 + 12.56

Evaluate the sum

A = 18.84

Hence, the surface area of the cylinder with the given height and radius is 18.84 square feet

- x - x + 11 - 2x = 83<br>please show step by step!!​
m_a_m_a [10]

Answer:

x=-18

Step-by-step explanation:

<u>Given</u>

<u />-x-x+11-2x=83

<u>Step 1: Combine Like Terms on LHS</u>

<u />-x-x+11-2x=83\\-2x+11-2x=83\\-4x+11=83

<u>Step 2: Subtract 11 on both sides</u>

<u />-4x+11=83\\-4x+11-11=83-11\\-4x=72

<u>Step 3: Divide both sides by -4 to isolate the x-variable</u>

<u />-4x=72\\\\\frac{-4x}{-4}=\frac{72}{-4}\\ \\ x=-18

<u>Final Answer</u>

<u />x=-18
