Step-by-step explanation:
8/3 = 2.6666 (repeating 6)
so rounded about 2.7 minutes per lap :)
The diameter of the new rubber ball, to the nearest foot, must be D = 4.0 ft (in the case of the maximum cost).
<h3>
How to find the diameter of the ball?</h3>
Remember that for a sphere of diameter D, the surface area is:
A = 4*pi*(D/2)^2
In this case, the cost is $0.02 per square foot, and the company wants to expend (at maximum) $1 per ball, so first we need to solve:
$0.02*A = $1
A = $1/$0.02 = 50
So the surface of the ball must be 50 square feet.
Then we solve:
50ft^2 = 4*3.14*(D/2)^2
D = 2*√(50 ft^2/(4*3.14)) = 4.0 ft

Answer:
142.5 in^2
Step-by-step explanation:
First, find the area of the rectangle
19*10= 190
Now find the area of the triangle
A=1/2bh
A=1/2(19)(10-5)
A=47.5
Since we need the shaded region, subtract the triangle area from the rectangle area
190-47.5=142.5
