It takes 54 minutes for 4 people to paint 6 walls. how many minutes does it take 6 people to paint 7 walls?

The answer is 42

Step-by-step explanation:

im right because i copied the other person and they were all the way wrong so i pressed hint after i got the answer completely wrong the hint said the answer was 42 then i tried it and it is 42 and for those of you who are looking at this answer probably need help with Khan Academy so your welcome <3

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
