A middle school band held a car wash to raise money. if they washed 28 cars in 2 hours. At this rate, how many cars did they wash in 9 hours A.26

B.252

C.14

D.126

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

you could deduce the conclusion directly using the facts pertaining to the specific situation.

hope this .
