Answer:
option 3
Step-by-step explanation:
V= πr²h
to make h the subject
h= V÷πr²
just take πr² to the other side
as it in multiplication on the left hand side, it will in division in right hand side.
hope it helps!

Answer:
Step-by-step explanation:
Start by changing the dollars into cents.
2.07 dollars = 2.07 * 100 = 207 cents
1.64 dollars = 1.64 * 100 = 164 cents.
How much does 1 ounce cost for each?
207 cents / 48 = 4.3125 cents / oz
164 / 32 = 5.125
The better buy is the 48 fluid oz jar.

Answer:
8 units
Step-by-step explanation:
Displacement is the area under the velocity curve. The area of interest is in the shape of a trapezoid, so we can use the formula ...
A = (1/2)(b1 +b2)h
to find the area.
Here, b1=3, b2=1, h=4, so the area is ...
A = (1/2)(3 +1)(4) = 8
The displacement is 8 units in the time from t=1 to t=4.
