Arain gutter is made from sheets of aluminum that are 20 inches wide by turning up the edges to form right angles. determine the depth of the gutter that will maximize its cross sectional area to allow the greatest amount of water to flow

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

why? because i noticed a pattern. 60 120. those numbers without the zero, make the 6 times tables leaving your answer to be b since 6 times 4 is 24 and adding a zero making it 240.
