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

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:

  • [tex]\boxed{\sf{153.86\ in^2}}[/tex]

Step-by-step explanation:

Given:

Use the area of the circle formula.

AREA OF THE CIRCLE FORMULA:

[tex]\Longrightarrow: \sf{A=\pi r^2}[/tex]

[tex]\Longrightarrow: \sf{\pi =3.14}[/tex]

[tex]\Longrightarrow: \sf{r=\dfrac{14}{2}=7}[/tex]

[tex]\Longrightarrow: \sf{3.14*7^2}[/tex]

Use the order of operations.

PEMDAS stands for:

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

BODMAS stands for:

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

[tex]\sf{3.14*7^2}[/tex]

First, solve exponents.

[tex]\Longrightarrow: \sf{7^2=7*7=49}[/tex]

[tex]\Longrightarrow: \sf{3.14*49}[/tex]

Then, multiply.

[tex]\sf{3.14*49=\boxed{\sf{153.86}}[/tex]

Solutions:

[tex]\Longrightarrow: \boxed{\sf{153.86\ in^2}}[/tex]

  • Therefore, the correct answer is 153.86 in².

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