Chapter 12, Problem 2STP

To determine

To Calculate :Radius of the circle.

Answer to Problem 2STP

  $(4)4.9$

Explanation of Solution

Given information :

We know that, Coordinates of end points of diameter are given.

Formula Used:

Distance formula.

Calculation:

Using distance formula,

Diameter = $\sqrt{{(4+3)}^2+{(64)}^2}$

  $\begin{array}{l}=7\sqrt{2}\\ \therefore 2\rho =7\sqrt{2}\\ \therefore r=\frac{7\times \sqrt{2}}{2}\\ =4.9\end{array}$
