andre [41]

3 11/30

steps to this: here you have to  Rewrite our equation with parts separated

=1+15+2+16

Solving the whole number parts

1+2=3

Solving the fraction parts

15+16=?

Find the LCD of 1/5 and 1/6 and rewrite to solve with the equivalent fractions.

LCD = 30

630+530=1130

Combining the whole and fraction parts

3+1130=31130

Solution by Formulas

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

65+136

Applying the fractions formula for addition,

=(6×6)+(13×5)5×6

=36+6530

=10130

Simplifying 101/30, the answer is

=31130

Calculate the volume of a cylinder of radius 5cm and height 14cm (take pie 22/7)
HACTEHA [7]

Answer:

<em>Volume of a cylinder = 1,100cm³</em>

Step-by-step explanation:

<em>Volume</em><em> of</em><em> a</em><em> cylinder</em><em> </em><em>=</em><em> </em><em>πr²</em><em>h</em>

<em>Given</em>

<em>π </em><em>=</em><em> </em><em>2</em><em>2</em><em>/</em><em>7</em>

<em>r </em><em>=</em><em> </em><em>5</em><em>c</em><em>m</em>

<em>h </em><em>=</em><em> </em><em>1</em><em>4</em><em>c</em><em>m</em>

<em>Substitute</em><em> the</em><em> </em><em>given</em><em> </em><em>information</em><em> </em><em>in</em><em> the</em><em> </em><em>problem</em><em>.</em>

<em>Volume</em><em> of</em><em> a</em><em> cylinder</em><em> </em><em>=</em><em> </em><em>2</em><em>2</em><em>/</em><em>7</em><em> </em><em>×</em><em> </em><em>(</em><em>5</em><em>c</em><em>m</em><em>)</em><em>²</em><em> </em><em>×</em><em> </em><em>1</em><em>4</em><em>c</em><em>m</em>

<em>Volume</em><em> of</em><em> a</em><em> cylinder</em><em> </em><em>=</em><em> </em><em>2</em><em>2</em><em>/</em><em>7</em><em> </em><em>×</em><em> </em><em>2</em><em>5</em><em>c</em><em>m</em><em>²</em><em> </em><em>×</em><em> </em><em>1</em><em>4</em><em>c</em><em>m</em>

<em>Volume</em><em> of</em><em> a</em><em> </em><em>cylinder </em><em>=</em><em> </em><em>1</em><em>,</em><em>100c</em><em>m</em><em>³</em>
