If 25% of a number is 85 and 80% of the same number is 272, find 55% of that number.

170

Step-by-step explanation:

If 25% is 85 then multiply 25% by 2 to get 50% and 85 by 2 to get 179

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
