A painted water tower is shown. What percent of the surface area of the water tower (not including the surface underneath the tower) is green? Round your answer to the nearest tenth of a percent.

43.6%

Step-by-step explanation:

curved surface area (green) is found by circumference multiply by height

x d x h = x (15 x 2) x 12 = 360

total surface area is

blue circle + total curved surface area (blue + green)

= + 15(2)(8) + 360

= + 240 + 360

= 825

percentage = 360/825 x 100%= 22/55 x 100% = 43.63

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

answer: sorry i can't you.
