Step-by-step explanation:

<em>Here</em><em>,</em>

<em>radius</em><em> </em><em>of</em><em> </em><em>a</em><em> </em><em>cylinder</em><em> </em><em>(</em><em>r</em><em>)</em><em>=</em><em> </em><em>8</em><em> </em><em>ft</em><em>.</em>

<em>height</em><em> </em><em>(</em><em>h</em><em>)</em><em>=</em><em> </em><em>5</em><em> </em><em>ft</em><em>.</em>

<em>now</em><em>,</em>

<em>area</em><em> </em><em>of</em><em> </em><em>a</em><em> </em><em>cylinder</em><em> </em><em>(</em><em>a</em><em>)</em><em>=</em><em> </em><em>2.pi.r</em><em>(</em><em>r</em><em>+</em><em>h</em><em>)</em>

<em>now</em><em>,</em><em> </em><em>putting</em><em> </em><em>the</em><em> </em><em>values</em><em> </em><em>we</em><em> </em><em>get</em><em>,</em>

<em>a</em><em> </em><em>=</em><em> </em><em>2</em><em>×</em><em>3</em><em>.</em><em>1</em><em>4</em><em>×</em><em>8</em><em>(</em><em>8</em><em>+</em><em>5</em><em>)</em>

<em>after</em><em> </em><em>simplification</em><em> </em><em>we</em><em> </em><em>get</em><em>,</em>

<em>A</em><em>rea</em><em> </em><em>of</em><em> </em><em>cylinder</em><em> </em><em>is</em><em> </em><em>6</em><em>5</em><em>3</em><em>.</em><em>1</em><em>2</em><em> </em><em>sq.ft</em><em>.</em>

Should it be facing left or right ?
riadik2000 [5.3K]

Answer:

Facing Right

Step-by-step explanation:

Given inequalities are:

4-x≤-1

Subtracting 4 from both sides

4-x-4≤-1-4

-x≤-5

Multiplying both sides with -1. Multiplying with a negative number changes the sign of the inequality

So,

x≥5

Second Inequality:

2+3x≥17

Subtracting 2 from both sides

2+3x-2≥17-2

3x≥15

Dividing both sides by 3

x≥5

Union of both solutions:

x≥5 ∩ x≥5

=> x≥5

Hence the solution will be facing right on the number line towards all numbers greater than or equals to 5 ..
