What is the exact circumference of a circle with a radius of 12 inches? O 6 in.
O 12 in.
O 24in.
O 48 in.

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

y=-2x+1500

step-by-step explanation:

+1500

2 over one
