Answer:
9.82 feet
Step-by-step explanation:
the perimeter of the window is the circumference of a semi-circle with a diameter of 5
P = (πd)/2 (divided in half because it's only half a circle)
P ≈ 3.14(3.5) which is approx 11
11 is closest to 9.82
So you basically plug in the x value beside the 5 so if your on number 3 the answer would be 5(3) which is 15

Find the height of it with pythagoras
Root(100-36)=8
Volume = 1/3 pi r^2 h
1/3(36pi x 8)
=96pi
about 301.59ft^3
Answer:
See below.
Step-by-step explanation:
Let x equal each of the values on the table, and find the value of the function for that value of x.
f(x) = 5x - 5
x = -4
f(-4) = 5(-4) - 5
f(-4) = -20 - 5
f(-4) = -25
x = 0
f(0) = 5(0) - 5
f(0) = 0 - 5
f(0) = -5
x = 1
f(1) = 5(1) - 5
f(1) = 5 - 5
f(1) = 0
x = 3
f(3) = 5(3) - 5
f(3) = 15 - 5
f(3) = 10
x = 5
f(5) = 5(5) - 5
f(5) = 25 - 5
f(5) = 20
x f(x)
-4 -25
0 5
1 0
3 10
5 20
