Chapter 11.7, Problem 10WE

To determine

To Find: The ratio of their diameter and circumference.

Answer to Problem 10WE

  $\frac{3}{4}$

Explanation of Solution

Given: The area of two circles are $36\pi and64\pi$

Given: area= $36\pi and64\pi$

Ratio of areas are

  $\frac{36\pi }{64\pi }=\frac{9}{16}=\frac{3}{4}$

Thus the scalar factor is $\frac{3}{4}$

Therefore

The ratio of diameter and circumference is same which is $\frac{3}{4}$ .
