The area of lens is 3.14 square yards.
Step-by-step explanation:
Given,
Circumference of lens = 6.28 yards
Circumference = 2πr
[tex]6.28=2*3.14*r\\6.28=6.28r\\6.28r=6.28[/tex]
Dividing both sides by 6.28
[tex]\frac{6.28r}{6.28}=\frac{6.28}{6.28}\\r=1[/tex]
Area of lens = πr²
Area of lens = [tex]3.14*(1)^2=3.14*1[/tex]
Area of lens = 3.14 square yards
The area of lens is 3.14 square yards.
