Question 751440: A pizza parlor has two different sizes of pizza. The smaller one has a diameter of 10 inches and the larger one has a diameter of 16 inches. What is the ratio of the area of the smaller pizza to the area of the larger pizza?

Smaller pizza has diameter of 10 ins. Radius = 5 ins.
Larger pizza has diameter of 16 ins. Radius = 8 ins
Area of smaller pizza = pi*r^2 => 78.54 ins^2
Area of larger pizza = pi*r^2 => 201.06 ins^2
78.54 : 201.06
1 : 2.56
hope this helps.
