Step-by-step explanation:
the volume (V) of a cylinder is calculated using the formula
V = area of base × height
here the base is a circle with radius r = 2x²y
area of base = πr² = π × (2x²y)² = π × 4y² = 4y²π
V = 4y²π × 3x³
= 12y²π
Answer:
D: Day 18
Step-by-step explanation:
When their graphs intersect each other, that is when they have the same amount left to sell.
Answer:
A = P * a / 2
A = 81.25
Step-by-step explanation:
We have that there is a corresponding formula for a regular decagon, which depends on the apothem and the perimeter, it is the following:
A = P * a / 2
In this case, the perimeter is the sum of all the sides, that is, 10 sides, therefore:
P = 10 * 3.25
P = 32.5 meters
We replace:
A = 32.5 * 5/2
A = 81.25
Which means that for that regular decagon, the area is 81.25 square meters.
