Chapter 9.1, Problem 11CE

To determine

To find the diameter of a circle with given radii

Answer to Problem 11CE

if radius $=14$ then diameter $=28$

if radius $=13$ then diameter $=26$

if radius $=5.6$ then diameter $=11.2$

if radius $=6n$ then diameter $=12n$ .

Explanation of Solution

Given information :

Radii $14,13,5.6\text{and}6n$

Since diameter is the twice length of radius.

i.e. $\text{diameter}=2\times \text{radius}$

Therefore, if radius $=14$ then diameter $=28$

if radius $=13$ then diameter $=26$

if radius $=5.6$ then diameter $=11.2$

if radius $=6n$ then diameter $=12n$ .
