Question

Saul’s Chapeau Shop sells sleek sombreros
Saturdays and Sundays. The hats come in a variety
of sizes. The starting hat size has a diameter of
10 inches, and costs $4.00 . Each extra inch of brim
added to the diameter of the hat costs $0.75. The
largest diameter hat a customer can purchase is 48
inches.

If each sombrero is a circle, which of the
following represents the greatest area possible
in square inches:
a. 48 pie
b. 100 pie
c. 361 pie
d. 576 pie
e. 1152 pie
note:pie as in 3.14...... i dont have pie symbol :)

Answer 1

i believe it is d. is it right?

Answer 2

Thats correct. Radius is 1/2 of the diameter, so r=24inches. The area of a circle is pi*r^2, so 576pi.

Answer 3

THANKS!
