a circular harkness table is placed in a corner of a room so that it touches both walls. a mark is made on the edge of the table, exactly 18 inches from one wall and 25 inches from the other. what is the radius of the table?

Answer :

The radius of table can be 13 inches or 73 inches.

Let r inches be the table's radius.

Make the corner the starting point or origin.

the coordinates for the table's center are as follows: (r, r).

So  [tex](x-r)^{2} +(y-r)^{2}=r^{2}[/tex]  is the equation for the table's diameter.

The distance between the mark at the table's edge and one wall is 18 inches and 25 inches, respectively. Consequently, this point's coordinates are (18, 25). It might alternatively be (25, 18), but our calculations would not be affected.

Given that the mark is on the edge, it satisfies the criteria established by the table's circumference equation.

[tex](18-r)^{2} +(25-r)^{2} =x^{2}[/tex]

[tex]324-36r+r^{2} +625-50r+x^{2} =x^{2}[/tex]

[tex]r^{2} -86r+949=0[/tex]

(r−13)(r−73)=0

r=13 inches or r=73 inches

As a result, the table's radius can be either 13 inches or 73 inches.
