Answer: The volume of cylinder Q is 12 times the volume of Cylinder P.
Step-by-step explanation:
The formula for determining the volume of a cylinder is expressed as
Volume = πr²h
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
If cylinder Q has radius, r and height, h,
Then
Volume of cylinder Q = πr²h
For cylinder P,
Height = 3h
Radius = 2r
Volume of cylinder P = π(2r)² × 3h
= 4πr²× 3h = 12πr²h
Therefore, the ratio of the volume of cylinder P to the volume of cylinder Q is
12πr²h/πr²h = 12

Answer:
d. 9x + 63 and 63 square feet
Step-by-step explanation:
Given
Original
Extended
Required
Determine an expression and the value of the extended area
First, we calculate the area of the original desk
From the given parameters, we have:
--- area of the new surface
Open bracket
The area of the new surface is the summation of the area of the original desk and the area of the extended portion (E)
So:
Make E the subject
Hence, the area of the extended portion is 63
