Answer:

2310m^3

Step-by-step explanation:

base area which is the circle = πr^2

But diameter, d = 14, r = 14/2 = 7

area = π × (7)^2 = 22/7 × 49 = 22 × 7 = 154

Volume = base area × height

= 154 × 15 = 2310

In 1990, the population of Boston, Massachusetts was 574,283. In 2000, the population was 589,141. What is the percent of change
MrMuchimi

Answer:

Percent of change in population is 2.6%

Step-by-step explanation:

Given population of Boston is 574,283 measured in year 1990.

And population of Boston in year 2000 is 589,141.

We need to find percent of change in population.

So, percent change =\frac{New\ population-Old\ population}{Old\ population}\times100%

Here old population is 574,283 and new population is 589,141

Plugging these value in formula we get,

Percent change =\frac{589,141-574,283}{574,283}\times100\\\\=\frac{14858}{574,283}\times100=0.0258\times100\\\\=2.587

Rounding to nearest tenth 2.6%
