Answer:
Step-by-step explanation:
If it goes 220 meters and has made 100 revolutions that means that each revolution is 220 meters / 100 = 2.2 meters.
That's the same thing as saying that the wheel has a circumference of 2.2 meters.
Circumference = 2*pi * r = pi * d
2 = pi * d
2 = 3.14 * d
2/3.14 = d
d = 0.6369 meters
Answer:
x= -1
Step-by-step explanation:
x+5=4 or x+5= -4
x= -9 or x= -1
Answer: The radius would be twelve
Step-by-step explanation:
The radius of a sphere would be 12 cm. By putting the value of volume we can find the radius of the sphere. The radius of a sphere would be 12 cm.
(15 minutes/hour) x (1 spot / 1/2 minute) x (24 hour/day) = <u><em>720</em></u> spots/day
