Answer: 4in
Step-by-step explanation:
Volume of a cylinder = πR²H
Volume of a cone = 1/3πr²h
πR²H = 1/3πr²h
π is very common so it could be cancelled, so the equation now becomes
R²H = 1/3r²h
3R²H = r²h
Now substitute for the values
h = 3 x 2² x 3
--------------
3²
= 9 x 4/9
= 4in.
Therefore, the height of the cone
h = 4in.
Answer:
f(x) = 7x^9-3x^2-6
Step-by-step explanation:
Discounts are used to reduce the original price of an item.
David will pay $25 and 92 cents for an item of $32, before tax
The discount (d) is given as:

The price (p) of the item is given as:

So, the amount (A) paid before tax is calculated using:

Substitute known values

Express percentage as decimal

Subtract 0.19 from 1

Multiply 32 and 0.81

Hence, David will pay $25 and 92 cents for an item of $32, before tax
