A globe has a diameter of 22 in. What is the best approximation for the volume of this globe?

1 answer:

8 0

Sphere Volume = ( π • d³) / 6
Sphere Volume = (3.14159265 * 22^3 / 6)

Sphere Volume = 5,575.2797

It seems they used PI = 3.14 because then the answer is:
 5,572.45

Before the election, you want to determine the number of possible president/vice-president combinations for the sorority you bel

vichka [17]

Solution: We have to choose two positions president and vice president from eight people. So, we need to use the Permutations formula in order to find the possible number of combinations.

The number of possible combinations is:

8P2 $=\frac{8!}{(8-2)!}$

$=\frac{8\times7\times6\times5\times4\times3\times2\times1}{6\times5\times4\times3\times2\times1}$

$=\frac{40320}{720}$

$=56$

Therefore the possible number of combination to select two positions from 8 people is 56
