[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.
