r = 3
Step-by-step explanation:
225 divided by 25 is 9 which is diameter
radius is half of the diameter which is 3
to find the radius you the formula of how to the volume of a cylinder then you flip it around.

Answer:
The first one is a line because a line extends infinitely in both directions which the arrows indicate.
The second one is a plane since it is a 2-dimensional shape.
The last one depicts 2 rays because rays have one endpoint, but extend infinitely in the other direction.
4 miles in 1 hour.
1 mile will be covered in (1/4) hour.
22 miles will then be covered in: 22 * 1/4 = 11/2 = 5.5
22 miles will be covered in 5.5 hours.
Answer:
x=39, y=180
Step-by-step explanation:
f(x)=0.4x²-31.2x+788.4
For x=39 the graph reaches its lowest point.
The minimum value of y is:
x=39→y=f(39)=0.4(39)²-31.2(39)+788.4
y=f(39)=0.4(1,521)-1,216.8+788.4
y=f(39)=608.4-1,216.8+788.4
y=f(39)=180
