Find the area of a circle with a circumference of 53.41 inches

Step-by-step explanation:

We are given the circumference.  The formula for circumference is  

C = πd     where d is the diameter and C is the circumference.

We are given C = 53.41, so we have...

53.41 = πd  

Solving for d gives us...

53.41/π = d    

The formula for area of a circle is  

A = π(r²)     where A is the area, and r is the radius

The radius is half of the diameter, so we divide 'd' by 2 to get the radius...

r = d/2 = (53.41/π)/2 = 26.705/π

The area of the circle is...

A = π(26.705/π)²

 A = π(26.705²/π²)

     A = 26.705²/π

       A = 227.0049315 in²

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
