Answer:
629.92 
Step-by-step explanation:
The minimum volume of the can that can hold 4 tennis balls must have at least the same volume as 4 tennis balls.
The volume of one tennis ball, V = 
where r = radius of the tennis ball
The diameter of a ball = 6.7 cm
Its radius will be = 6.7 / 2 = 3.35 cm
Volume, V, will be:

V = 157.48
Hence, the volume of 4 balls will be:
4 * V = 4 * 157.48 = 629.92 
The minimum volume that the cylindrical can has to have is 629.92
.
Answer:
119.43cm^2
Step-by-step explanation:
The computation of the area of the shaded region is shown below:
As we know that
= Area of the rectangle - Area of the circle
where,
Area of rectangle is


= 132 cm^2
And, the area of the circle is

Now the area of the shaded region is

= 119.43cm^2
We simply deduct the area of the circle from the area of the rectangle so that the area of the shaded region.
220pm=10w (people*minutes)
w=22pm
14w=308pm
308pm/14p=22m
So it would take 22 minutes for 14 people to paint 14 walls.
Answer: n-6p^2 + 2np
