The diameter of the circle is 4 inches so its radius r is 2 inches. The area of the circle is

$A = \pi r^2 = \pi(2\:\text{in})^2 = 12.57\:\text{in}^2$

The circumference C of the circle is

$C = 2\pi r = 2\pi(2\:\text{in}) = 12.57\:\text{in}$

Answer:

193.586 deaths per 100,000

Step-by-step explanation:

The cause-specific mortality rate for a disease in a per 100,000 basis is determined as the total number of deaths due to the disease multiplied by 100,000 and divided by the average (mid-year) total population.

There were 597,689 deaths due to diseases of the heart in a population of 308,745,538 people. The cause-specific mortality rate for diseases of the heart per 100,000 in this population is:

$M=\frac{597,689}{308,745,538}*100,000\\ M=193.586\ deaths/100,000$
