Which will cause an increase in mechanical energy of an object
A. Decreasing it kinetic energy
B. Increasing it electrical
energy
C. Increase its potential energy
D. Decrease it’s gravitational energy

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
