Step-by-step explanation:

1. using the formula for permutation

=10*9*8*7*6!/6!

Caden removed the label of a soup can like the one shown. What is the approximate area of the label if the can is 4 inches high

Dominik [7]

EXPLANATION

If the height of the can is 4 inches and the diameter is 3--> radius=1.5 inches, the area is given by the following relationhip:

$\text{Area}_{\text{label}}=2\pi rh$

Replacing terms:

$\text{Area}_{\text{label}}=2\pi\cdot1.5\cdot4=12\pi=37.7in^2$

The approximate area is 37.7 in^2
