5×60×20 use multiplication properties to find product and identify the property used

The product is 6,000 and the properties applied are: Commutative property of multiplication and Associative property of multiplication.

Step-by-step explanation:

1. The commutative property of multiplication says that the order of the factors does not change the product. Then:

2. The associative property of multiplication says that if you change the grouping of factors does not change the product, as you can see below:

paula, cory, and krista

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
