The area of a circle is 616cm find the radius​
Leokris [45]
<h3>Given :-</h3>

  • Area of Circle = 616 cm²

<h3>To Find :-</h3>

  • Radius of a circle = ?

<h3>Solution :-</h3>

☼︎ <u>Radius of the Circle</u>;

<h3>Using Formula:</h3>

\\ \red\bigstar {\underline{\boxed{\color{springgreen}{\textsf{ \textbf{ \: Area \: of \: circle= \:  \: π \:  r \: ² \: }}}}}} \\\\

<u>Putting values in the formula;</u>

\\  \sf \implies \: Area \:  =  \: \pi \: r \:  ^{2}  \\

\\  \sf \implies \: 616 \:  =  \:\frac{22}{7}  \times  \: r \:  ^{2}  \\

\\  \sf \implies \: 616 \: \times  \: \frac{7}{22}  \:  =  \: \: r \:  ^{2}  \\

\\  \sf \implies \:  \: \frac{ \:  \: 4312 \:  \: }{22}  \:  =  \: \: r \:  ^{2}  \\

\\  \sf \implies \:  \:  \cancel{\frac{ \:  \: 4312 \:  \: }{22}  }\:  =  \: \: r \:  ^{2}  \\

\\  \sf \implies \:  \:   \: 196 \:  \: =  \: \: r \:  ^{2}  \\

\\  \sf \implies \:  \:r \:  ^{2}  =    \: 196 \:  \:   \: \:  \\

\\  \sf \implies \:  \:r \:   =    \sqrt{ \: 196 \:  } \\

\\  \bf \implies \:  \:Radius  \:   =    14 \: cm \\

henceforth, the Radius of a circle is 14 cm ...!!

3(1 – 2x) &gt; 3 – 6х help
coldgirl [10]

Answer:

<h2>\huge \: x \in ∅</h2>

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about:</h3>
  • inequality
  • distribution
  • PEMDAS
<h3>given:</h3>
  • 3(1  -  2x) > 3 - 6x
<h3>to solve:</h3>
  • x
<h3>let's solve:</h3>

step - 1  : define\\ 3(1  -  2x) > 3 - 6x

step -  2: distribute\\ 3  -  6x > 3 - 6x

step - 3  :  \\ add \: 6x \: to \: both \: sides

3  -  6x  + 6x> 3 - 6x + 6x

3 > 3

\therefore \: the \: statement \: is \: false \: for \: any \: value \: of \: x \: because \: both \: sides \: are \: identical

therefore,

x \in ∅
