Question 193719: a circle has a diameter of 4'3 9/16" what is the area of the circle in square inches? what is the area in square feet?
a=pie(don't know where sign is on computer) a = pie x r2
r2= 51.5625 r = 25.78125in2 pie x 25.78125 in2 = 2087.07in2
so area of circle in2 = 2807.07in2?
area of circle in square feet = 28.9870ft2?
hope you can understand that! Thanks alot Tammy

Question 194000: Tow objects with volumes of 54cm3 and 108cm3. Find the ratio of the surface areas.
All of the problems that we have had in the past have a whole number as an answer. When I tried to solve this one I get 3.77976 for 54cm3 and 4.76220 for 108cm3. How do I convert it to a fraction or is there a step that I am missing?
