How does the volume of a cylinder change when its diameter is halved

Mathematics
1 answer:
Ivahew [28]3 years ago
7 0

The volume of a cylinder is given by πr²h where, r is the radius of the cylinder and <span>h </span>is the height of the cylinder.

Also<span> r=d/2</span> , where d is the diameter of the cylinder.

Therefore if the diameter is halved, the radius also gets halved ,i.e., it becomes r/2. Therefore the new volume =<span> π(r/2)²h</span>

=π(r²/4)h

<span>=(1/4) πr²h</span>

<span>
</span>

the perimeter of a square is 20 ft if you increase the length of the square by 2 feet and decrease the width by 1ft what is the
IrinaVladis [17]

Answer:

28 ft squared

Step-by-step explanation:

The 4 sides of a square are equal in length, so if the perimeter is 20ft that means each side would have to be 5ft, (20/4 = 5). If you increase the length by 2ft, one of the sides would now become 7ft (5+2 = 7). If you decrease the length of the other side by 1ft, the length would now be 4ft (5-1=4). Now to find the area, all you have to do is length * width. So you would do 7ft*4ft which is 28ft squared.
