Kiley would need glass of area between 3.14 and 12.56 square feet
Step-by-step explanation:
The Circumference of the circle is given by 2πr where “r” is the radius
Range of the circle’s circumference- 6.28 feet to 12.56 feet
Considering lowest radius as r₁ and the largest as r₂
2πr₁= 6.28
∴r₁= 6.28/(3.14*2) = 1 feet
Similarly
⇒2πr₂=12.56/(3.14*2)=2 feet
We know that area of the circle is given by πr
²
Area of the circle= 3.14*(1)² = 3.14 square feet
Area of the largest radius= 3.14*(2)²= 12.56 square feet
Hence Kiley would need glass of area between 3.14 and 12.56 square feet
