Find k(3) for the function k(n) =2n²

k(3) = 18

Step-by-step explanation:

k(n) = 2n²

k(3) = 2 * (3)²

k(3) = 2 * 9

k(3) = 18

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
