Find the value of X. Please help ASAP

Step-by-step explanation:

From the shape of the quadrilateral, we can assume that it is a parallelogram. In a parallelogram, opposite sides are congruent and thus have the same length.

In this case, we are given that two opposite sides have lengths of and . Therefore, since the quantities must be equal, we can write the following equation to solve for : . Solving for , we get:

(Use the Subtraction Property of Equality to subtract from both sides of the equation, which isolates )

(Use the Division Property of Equality to divide both sides of the equation by to get rid of 's coefficient)

Hope this helps!

R = 6

Step-by-step explanation:

Remember... Circle area is:

A = pi×R^2

Where R is the circle radius.

Then,

Pi×R^2=36×Pi

R = square root of 36

R = 6
