Answer:
50.3 cm³
Step-by-step explanation:
Use the cylinder volume formula:
V = 
r²h, where r is the radius and h is the height.
Since the radius is half of the diameter, and the cylinder has a diameter of 4 cm, this means the radius is 2 cm.
Plug in the radius and height into the equation:
V = r²h
V = (2²)(4)
V = 16
V = 50.3 cm³
Answer:
p = 1
Step-by-step explanation:
Δ JKH ≅ Δ JIH
therefore KJ corresponds with IJ so you can set both sides equal to each other
10p = p+9
9p = 9
p = 1
By better I am assuming you meant faster so,
18 ÷ 2 = 9
22 ÷ 2.5 = 8.8
9 > 8.8
therefore Emily has the faster rate.
