The radius of a circle with an area of π/4 square units is B. 0.5 units
<h3>What is an area?</h3>
Area is the quantity that expresses the extent of a region on the plane or on a curved surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of the three-dimensional object.
Now it is given that,
Area of circle = π/4 square units
Since we know that,
Area of circle = πr²
where r is the radius of circle.
⇒ r² = Area of circle / π
Put the values we get,
⇒ r² = (π/4)/ π
⇒ r² = 1/4
Taking square root both the side we get,
⇒ r = 1/2 units
or, r = 0.5 units
Thus, the radius of a circle with an area of π/4 square units is B. 0.5 units
