Answer: 109.5 km/ hr
Step-by-step explanation:
Distance = 73 km
Time = 40 minutes = 40/60 = 2/3 hours
Speed = Distance / time
= 73 / 2/3
= 73 x 3/2 = 219 / 2 = 109.5 km/hr
Here,
Volume of cylinder = 539^3 cm
Circumference = 22 cm
Height = ?
Now,
Circumference = 2πr
or, 22 = 2*22/7*r
or, 22 = 44/7*r
or, 154/44 = r
◆ r = 3.5 cm
Then,
Volume of cylinder = πr^2h
or, 539 = 22/7*(3.5)^2*h
or, 539 = 22/7*12.25*h
or, 539 = 269.5/7*h
or, 3773 = 269.5*h
or, 3773/269.5 = h
◆ h = 14 cm
