Answer:

Correct answer: V = 486 π ft³

Step-by-step explanation:

Given:

Diameter of the sphere d = 18 ft

d = 2 · r where r is radius

r = d / 2 = 18 / 2 = 9 ft

r = 9 ft

V = (2/3) · r³· π

V = (2/3) · 9³ · π = (2/3) · 729 · π = 486 π ft³

V = 486 π ft³

What is the sum of an infinite geometric series if the first term is 81 and the common ratio is 2⁄3?

Marrrta [24]

the sum to infinity of a geometric series = $\frac{a}{1-r}$

where a is the first term and r the common ratio

= $\frac{81}{\frac{1}{3} }$ = 81 × 3 = 243

Computer usage has increased over time. But has the increase been more linear or more exponential? In 1997, 22.2% of the populat

denis23 [38]

That's an increase of 30,000,000 people in one year, a slope of 30 million and a good year for the internet.

If t is the year, and p is number of internet users,

p = 30000000(t - 1997) + 60000000

Answer: p = 30000000(t - 1997) + 60000000

As for linear versus exponential, one year of data can't really distinguish.
