Abus on a regular schedule takes 3 1/4 hours to reach its destination. the express bus takes 2 1/2 hours to make the same trip. how much travel time can be saved by taking the express? a. 1 1/4 hours b. 3/4 hour c. 2 hours d. 5 3/4 hours it c right?

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
