Please help me out!?????

Answer
[tex]\frac{121}{4} \pi mm^2[/tex]
Explanation
Find the radius
11/2 = 5.5
The formula to find the area of a circle is [tex]\pi r^2[/tex]
[tex]\pi 5.5^2[/tex] = [tex]30.25\pi[/tex]
Convert number into fraction.
[tex]30.25 \rightarrow \frac{121}{4} \pi[/tex]
Area = [tex]\frac{121}{4} \pi mm^2[/tex]
Answer:
30.25π mm²
Step-by-step explanation:
The area (A) of a circle is calculated using the formula
A = πr² ← r is the radius
here diameter = 11 and radius is half of the diameter. thus
r = 5.5
A = π × 5.5² = 30.25π mm²
