Find the least common multiple (LCM) to determine the least common denominator for 2/3, 5/6, and 9/4

LCM = 12

Step-by-step explanation:

First, we find the prime factorizations of the numbers.

3 = 3

6 = 2 * 3

4 = 2^2

For the LCM, we choose common and not common factors with the larger exponent.

We need 2^2 and 3.

LCM = 2^4 * 3 = 4 * 3 = 12

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
