A cylinder has a height of 14 feet. Its volume is 12,704.44 cubic feet. What is the radius of the cylinder?
Alenkinab [10]
<h3 /><h3>V. Cylinder =  π . r² . h</h3>

12,704.44 = 3.14 × r² × 14

12,704.44 = 3.14 × 14 × r²

12,704.44 = 43.96 × r²

r² = 12,704.44/43.96

r² = 289

r = √289

r = 17

Question 12 1 pts If the population of a country is reported in the year 1990 as 471.56 million and in the year 2000 as 492.53 m
I am Lyosha [343]

Answer:

  526.39 million

Step-by-step explanation:

The exponential equation can be written as ...

  p(t) = 471.56(492.53/471.56)^(t/10)

Then p(25) ≈ 525.75 . . . . million

__

The closest answer choice is 526.39 million.

__

<em>Comment on the answer choice</em>

Reverse-engineering the answer, we find it was computed using the exponential equation ...

  p(t) = 471.56e^(0.0044t)

  p(25) = 471.56·1.116278 ≈ 526.39

The k factor in the exponent is <em>inappropriately rounded</em> from 0.004350903. You cannot use a 2-significant-figure constant to arrive at an accurate 5-significant-figure answer.
