Answer:
86.625 cm²
Step-by-step explanation:
Find the length of the wire:
Length = 11 + 11 + 11 = 33 cm
Find the radius:
Circumference = 2πr
33 = 2πr
r = 33/2π
r = 5.25 cm
Find the area:
Area = πr²
Area = π(5.25)² = 86.625 cm²
Answer: The area is 86.625 cm²

With the best explanation.
According to the question we know that side of triangle is 11 cm .and triangle is a equilateral triangle so, the length is 11*3 = 33 we, need to find area or radius
Now,
Radius of circumference is 2πr
Then, area of circumference is πr²
