volume = π x r^2 x h
diameter = 20, radius = 20/2 = 10
10^2 = 100
100 * 5 = 500
volume = 500π cubic cm

Answer:
b. 61.75
Step-by-step explanation:
Split it into a rectangle and a triangle
1. Rectangle
You can see that the side lengths are 7 and 6.5, so the area is 7 * 6.5 = 45.5
2. Triangle
You know that the base is 6.5 and that the height is 5 (because 12 - 7 = 5) so you can find the area by doing 6.5 * 5 / 2 = 16.25
3. Total
Add the two areas, so 45.5 + 16.25 = 61.75
Answer:
The depth of the water is increasing by <u>2</u> feet each minute
Step-by-step explanation:
y-axis represents the depth of the water (in feet) and x-axis represents time (in minutes)
To answer the question we need to find the slope of the line. Given that the line goes through points (2, 4) and (4, 8), its slope is:
slope = (y2 - y1)/(x2 - x1) = (8 - 4)/(4 - 2) = 2
