Answer:
QR = 5.
Step-by-step explanation:
Because the parallelograms are similar then the corresponding sides are in the same ratio.
So AB / PQ = BC / QR
9/3 = 15 / QR
15 / QR = 3
QR = 15/3
= 5. (answer)

Answer:
20 km/hr
Step-by-step explanation:
Hey
Distance= 15km
Time= 45min
Since the unit for time is hours, we will convert 45 minutes to hours
45/60 = 0.75 hours
Speed= d/t
= 15/0.75
= 1500/75
= 20 km/h
Hope this helps
Answer:
236.22 cubic centimeters
Step-by-step explanation:
We need to find volume of 3 tennis balls and subtract it from volume of the cylinder to get our answer.
Volume of sphere (tennis ball) = 
<u>Note:</u> Radius is half of diameter, which is r = 6.7/2 = 3.35
Volume of 3 tennis balls = 
Volume of Cylinder = 
<u>Note:</u> radius is 3.35 and height is diameter of 3 tennis balls stacked on top of each other, so height is 6.7 * 3 = 20.1
Hence,
Volume of Cylinder = 
amount of space not taken up = 708.66 - 472.44 = 236.22 cubic centimeters
