Answer: Choice D) 1661 cm^2
========================================================
Explanation:
The diameter is 46 cm, which cuts in half to the radius of 23 cm.
area = pi*(radius)^2
A = pi*r^2
A = pi*23^2
A = pi*529
A = 529pi
This is the exact area in terms of pi.
--------
From here, replace pi with an approximation such as 3.14
529*pi = 529*3.14 = 1661.06
This value is approximate of course. To get a better approximation, use more decimal digits of pi.
This then rounds to 1661 square cm.
