## Answers ( )

Answer:The correct answer is option (b).Therefore the area of the circle issquare unitsStep-by-step explanation:Given that , P(3,2) and Q(7,10) are the endpoint of the diameter of a circle.

To find out the length of diameter we use the distance formula.

If (x₁,y₁) and (x₂,y₂) are point.

Then the distance between them is =

Here x₁=3,y₁=2,x₂ = 7,y₂=10.

The length of the diameter is =

units.

Radius of a circle

Therefore the the radius of the circle is units units units

The area of a circle =

Therefore the area of the circle issquare units
