The change is (1/2 -1)*100% = -50% per period. Negative indicates a decrease of 50% per period.
Points W, Y and Z form a right triangle, so we can find the length of c by using the Pythagorean theorem.
Using YZ as the base and YW as the side we get:
C = √(3^2 + 4^2)
C = √(9+16)
C = √25
C = 5 units
15/4 would be your answer
We need the height of the cone
what we do is we know that when height is 10, V=something, so solve for the diameter is at that point and compare it to 24, the full height
sorry if confusing
V=(1/3)hpir^2
when h=10
160pi/3=1/3(10)pir^2
ties 3 both sides
160pi=10pir^2
divide by 10pi
16=r^2
sqrt both sides
r=4
at that point, the radius is 4
the real radius of the ful is 24/2=12
4/12=1/3
it is 1/3 full
if 1/3=160pi/3cm
2/3=320pi/3cm^3
needs 320pi/3 cm^3
