Answer:

2.496cm

Step-by-step explanation:

Volume of the cylindrical water bottle. Can be calculated with the equation below

V=πr^2h

Where

h= height

r= radius

Then substitute the values into the equation we have

147= 3.14 × r^2 × 7.5

147= 23.565 r^2

Make r^2 subject of the formula

r^2= 147/ 23.565

r^2= 6.23

r= √6.23

r= 2.496cm

A shape is rotated counterclockwise 110 degrees about the origin. What is another way to describe the rotation?
Kitty [74]

At max a rotation can be equal to π or 180°

So if it's rotated 110° counterclockwise then it's equal to rotation of supplementary angle clockwise

Supplementary angle=180-110=70°

70° rotation clockwise

B is the midpoint

\\ \sf\longmapsto AB=\dfrac{1}{2}AC

\\ \sf\longmapsto 7x-3=\dfrac{5}{2}

\\ \sf\longmapsto 5=2(7x-3)

\\ \sf\longmapsto 5=14x-6

\\ \sf\longmapsto 14x=6+5

\\ \sf\longmapsto 14x=11

\\ \sf\longmapsto x=\dfrac{11}{14}

\\ \sf\longmapsto x=7.8

Which best explains if quadrilateral WXYZ can be a parallelogram?
nekit [7.7K]

A quadrilateral in which opposite sides are parallel is called a parallelogram. The correct option is A.

<h3>What is a parallelogram?</h3>

A quadrilateral in which opposite sides are parallel is called a parallelogram. Thus, a parallelogram is always a quadrilateral but a quadrilateral can or cannot be a parallelogram.

For a parallelogram, the pair of opposite sides are equal and parallel. Therefore,

1.)  For the first pair.

(x+8) = 15

x = 7

2.) For the second pair

(x+2)=(2x-5)

x + 2 = 2x - 5

2 + 5 = 2x - x

x = 7

(x+2) = (7+2) = 9

Since the measure of the pair of opposite sides is 15 units, the pair of the other two sides measure 9 units.

Hence, the correct option is A.

The complete question is mentioned in the below image.
