The Formula's for a cylinder is V=
r^2h and the volume of a Cone is V=1/3
r^2h. So you would know that the volume of a cone is 1/3 the volume of a cylinder.
Answer:
For the function
y = cos(1/2 x)
The x-intercept can be calculated by equating the function to zero and solving for x. So,
y = cos(1/2 x) = 0
1/2 x = arc cos 0
1/2 x = 90° +180°n
x =2 (90° +180°n)
x = 180° + 360°n
or converting to radians
x = (180° + 360° n)(π/180°)
x = π + 2π n
where n is any whole number
if n = 0
x = π
Therefore, the x-intercept is π or π+2π n

Answer:
$45
Step-by-step explanation:
The sale price changed from $80 to 60, then with the coupon another 25% was taken off leading it to come to a price of $45
$80 x .75 = 60
$60 x .75 = 45
(.75 is for the price of the original value that he will be paying later)
Each package weighs 6 pounds. Choose the best estimate of the total weight of the packages.2,400 pounds 240 pounds 200 pounds 20 pounds.
5
The reason is because |-5| is equal to 5. The absolute value bars make the number positive.
