Question 918440: A Norman window has the shape of a rectangle surmounted by a semicircle. If the perimeter of the window is 36.900 ft. give the area A of the window in square feet when the width is 7.500 ft. Give the answer to two decimal places.
I'm stuck and I need this one to finish my homework! Even my dad can't help me and I got no results from google and my math book only uses rectangular examples!!! PLEASE HELP ME!!!! Answer by josgarithmetic(39617) (Show Source):
You can put this solution on YOUR website! The problem description is somewhat ambiguous. Width of the window is 7.500 feet; but is THE semicircle attached to a width or is it attached to a length? Any figure or diagram included in your book or page might help tell you this nonverbally.
I can explain generally.
x and y are the dimensions of the rectangle portion of the window. You know perimeter of the window p and one of the diensions, either x or y;
but you do not know A area of the window.
p=36.9000
A is unknown
either x or y is known but not both.
Either x or y serves as diameter of the semicricle, but only one of those dimensions; NOT both, and not both at the same time.
If the semicircle has diameter of y, then , and .
Nothing more specific without the exact and complete problem description.
