Water is falling on a surface, wetting a circular area that is expanding at a rate of 6mm^2/s. How fast is the radius of the wet
ted area expanding when the radius is 109nm. (Round your answer to four decimal places.)
1 answer:
Answer:
0.0622ns
Step-by-step explanation:
Rate, R = 6mm²/s or 6 X 10∧-8m²/s
Radius, r = 109 X 10∧-9m
Area of circular object = πr² = 22/7 X (109 X 10∧-9)²= 3.734 X 10∧-14m²
Speed = 3.734 X 10∧-14m²/(6 X 10∧-8)m²/s = 0.0622ns

My answer is in the photo above
The total is 6400, but if subtracted, its 1400
1 gallon = 4 quarts
2570 x 4 = 10,280 quarts of gas
10280/7 = 1468.571 quarts per day
rounded to nearest hundredth is 1468.57 quarts
