\large\texttt{Answer\::}

pls refer to the explanation !


\large\texttt{Calculations\::}


\textsf{Area of a circle : $A=\pi r^2$}

We're asked to use 3.14 for pi , so we'll do just that .

We have the diameter , so we divide it by 2 to find the radius (remember , the radius is 1/2 of the diameter).

Plug in :

A=3.14*(7)²

A=3.14*49

Multiply :

A=153.86 inches²

Answer:


  • \boxed{\sf{153.86\ in^2}}

Explanation:

Given:

Use the area of the circle formula.

AREA OF THE CIRCLE FORMULA:


\Longrightarrow: \sf{A=\pi r^2}


\Longrightarrow: \sf{\pi =3.14}


\Longrightarrow: \sf{r=(14)/(2)=7}


\Longrightarrow: \sf{3.14*7^2}

Use the order of operations.

PEMDAS stands for:

  • Parentheses
  • Exponents
  • Multiply
  • Divide
  • Add
  • Subtract

BODMAS stands for:

  • Brackets
  • Order
  • Divide
  • Multiply
  • Add
  • Subtract


\sf{3.14*7^2}

First, solve exponents.


\Longrightarrow: \sf{7^2=7*7=49}


\Longrightarrow: \sf{3.14*49}

Then, multiply.


\sf{3.14*49=\boxed{\sf{153.86}}

Solutions:


\Longrightarrow: \boxed{\sf{153.86\ in^2}}

  • Therefore, the correct answer is 153.86 in².

I hope this helps, let me know if you have any questions.
