Hello, rcs!
A circular piece with a 1.8m diameter is cut from a 2m by 2m piece of cloth.
How much cloth is wasted?
Did I really have to draw you a picture?
The cloth has an area of:.$\displaystyle 2\times 2 \,=\,4\text{ m}^2$Code:_ *---------------------------* : |:::::::::::::::::::::::::::| : |:::::::::::* * *:::::::::::| : |:::::::* *:::::::| : |:::::* *:::::| : |::::* *::::| : |:::: ::::| |:::* *:::| 2 |:::* * - - - - *:::| |:::* 0.9 *:::| : |:::: ::::| : |::::* *::::| : |:::::* *:::::| : |:::::::* *:::::::| : |:::::::::::* * *:::::::::::| : |:::::::::::::::::::::::::::| - *---------------------------* : - - - - - - 2 - - - - - - :
The circle has a radius of $\displaystyle 0.9\text{ m.}$
Its area is:.$\displaystyle \pi(0.9^2) \,=\,0.81\pi\text{ m}^2$
The waste (shaded area) is:.$\displaystyle 4 - 0.81\pi\text{ m}^2$
