PLEASE HELP ASAP

Circular pizza pies at Pat's Pizza's come in 10-inch and 16-inch diameters.

Which is closest to the difference in the areas of the pizza pies?





A
129.12 inches

B
183.46 inches

C
122.46inches

D
142.96 inches

Answer 1

C

Explanation:

The area formula of a circle is A=
`\pi r^(2)`, where r (or radius) is equal 1/2 times diameter (or d/2). So pi times (10/2)^2= 78.54 and pi times (16/2)^2=201.06. 201.06-78.54 = about 122.52, which is closest to 122.46, or C.
