??a cross that is 1 inch wide???
Crust*
A = pi * r^2
A = 3.14 * 49
A = ?
A = 3.14 * 49
A = ?
The answer has to be 40.8 in.
Why?
3.14 * 49 = 153.86 = 153.9 square inches
3.14 * 49 = 153.86 = 153.9 square inches
Because I need to find the area of the crust not the whole pizza. The answers in the back on my book say it should come to 40.8 inches, but I don’t know how to solve it.
40.8 square inches*
A pizza crust has the same area that the whole pizza has.
LOL, I think she just wants the part you see from above
If D is 14 then the slimy area has diameter of 12 because you take and inch off each side.
so
area of a circle = pi d^2/4
(pi/4)(14^2-12^2)
sure enough 40.8
