Answer:
volume of cylinder
v = πr²
v = 22/7 x 21²
v = 1385.441 cm³
Step-by-step explanation:
Each cm is 5 m so multiply each cm by 5m
Therefore 30cm X 5m/cm = 150 m
Hiking every 12 days : 12,24,36
swimming every 6 days : 6,12
they will go both swimming and hiking 12 days from now
Time equal to distance divided by the speed. In this question, Sarah need 2 hours and 40 minutes(or 160 minutes) to loop around the north part of Lake Washington. The time for the same distance cutted by 6 minutes if the speed increased by 1km/h. The calculation would be:
time= distance/speed
distance= time*speed=
distance1= distance2
time1*speed1= time2*speed2
160min*speed1= (160min-6min)*(speed1+1km/h)
160 speed1= 154 speed1 + 154km/h
160 speed1- 154 speed1 = 154km/h
speed1= 154km/h /6= 25.67km/h
