A circle has a radius of 11.6 in. If the area is multiplied by 16, what happens to the circumference? The circumference is multiplied by 4.
The circumference is multiplied by 11.6.
The circumference is multiplied by 16.
The circumference is multiplied by 8.

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
