A square has a side that measures 5.5 units. What is the area of a circle with a circumference that equals the perimeter of the
Alexeev081 [22]

Answer:

Answer choice A) About 38.47 square units

Step-by-step explanation:

Since all four sides of a square have the same length, the perimeter of a square is just 4 times one of the side lengths. The perimeter of the square and therefore the circumference of the circle is 5.5*4=22. The circumference of a circle is 2 times the radius multiplied by pi. The radius of this circle is therefore:

\dfrac{22}{2\pi}\approx 3.503

Since the area of a circle is \pi r^2, the area of this circle is:

\pi \cdot 3.503^2= 3.14\cdot 12.271\approx 38.47

Hope this helps!

(3x-8)(2xsquared4x-9) multiply and write the result in descending order
RSB [31]
Hello there, you can proceed with the multiplication of these factors using the FOIL method (which stands for first, outer, inner and last) multiply I assume that by descending order, you mean by decreasing power. If it were so, the answer is 6(x^3)12(x^2)-16(x^2)32x-27x+72.
