Answer : 4.5 × 10⁴ square inches can be washed per hour.
Step-by-step explanation :
As we are given that an area can be washed at a rate of 4,900 cm²/min. Now we have to determine the square inches can be washed per hour.
Given conversions are:
1 cm = 0.39 in and 1 hr = 60 min
As, 1 cm² = (0.39)² in² and 1 min = 1/60 hr
So, 
Now we have to determine the square inches can be washed per hour.
As,
So, 
Therefore, 4.5 × 10⁴ square inches can be washed per hour.
Answer:
<h2>35×24 = 840in²</h2>
Step-by-step explanation:
<h3>height=35 in.</h3><h3>base = 24
<em><u>i</u></em><em><u>n</u></em><em><u>.</u></em><em><u> </u></em><em><u> </u></em></h3>
<em><u>then</u></em> <em>multiply</em>
72/4 = 18 (18)(2/3) = 12. The answer is $12.00 per hour
The surface area of a right cylinder is the sum of the areas of the lateral face and the circular bases. The lateral face is really just a rectangle with the same height as the cylinder and a length equal to the circumference of the circular base.
If the radius of the base is
and the height is
, then the surface area of the cylinder is
You're given that the area is
and the radius is
, so you have
