The area of lens is 3.14 square yards.

Step-by-step explanation:

Given,

Circumference of lens = 6.28 yards

Circumference = 2πr

$6.28=2*3.14*r\\6.28=6.28r\\6.28r=6.28$

Dividing both sides by 6.28

$\frac{6.28r}{6.28}=\frac{6.28}{6.28}\\r=1$

Area of lens = πr²

Area of lens = $3.14*(1)^2=3.14*1$

Area of lens = 3.14 square yards

The area of lens is 3.14 square yards.
