Answer:
B. 8.6 cm
Step-by-step explanation:
⅓*πr²h = Volume formula of a cone (V)
Volume of cone (V) = 225 cm³
diameter of cone (d) = 10 cm
radius of cone (r) = ½(10) = 5 cm
height (h) = ?
Plug in the values into the equation and solve for h
⅓ × π × 5² × h = 225
⅓ × π × 25 × h = 225
(25π × h)/3 = 225
Multiply both sides by 3
(25π × h)/3 × 3 = 225 × 3
25π × h = 675
Divide both sides by 25π
h = 675/25π
h ≈ 8.6 cm (nearest tenth)
Looks like you have to attach a picture. It wont work, because all you did was copy it.
The answer is -3.5
hope this helps, and have a fantastic day
The volume of the cone is 2880 m3.
The scale factor is 1/4.
The volume of the cone has the formula (1/3)π r² h.
A scale factor of 1/4 will reduce the dimensions by 1/4 which will result to a total volume reduction of (1/4)³ = 1/64
The new volume will be 45 m3
Answer:
P = 867(1.07)^t
Step-by-step explanation:
The population of muskrats oscillates 33 above and below average during the year, hitting the lowest value in january.
If the average value = 900 muskrats
Then the lowest = 900 - 33 = 867
It increases by 7 % each month
R = 7%
equation for the population p in terms of the months since january t will be
P = Po( 1 + R%)^t
P = 867( 1 + 0.07) ^t
P = 867(1.07)^t
