Answer: 125.6 cm³
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the volume of a cylinder:
Where h is the height and r is the radius.
2. Therefore, you only need to substitute the values of the radius and the height into the formula, as you can see below:
3. Then, the answer is: 125.6 cm³.
For this case we have a function of the form:
y = A (b) ^ x
Where,
A: initial amount
b: decrease rate
x: time
We have then:
b = 0.15
Therefore the percentage of decrease is:
(1-0.15) * 100 = 75%
Answer:
75%

Answer:
The coordinates of point D( 4,4)
Step-by-step explanation:
<u><em>Step(i):-</em></u>
Given points are E(10,4) and B(16,4)
'E' is the mid-point of segment BD
Let D(x₁, y₁) be a point
E = midpoint of segment BD
20 = x₁ + 16
20-16 = x₁
x₁ =4
<u><em>Step(ii):-</em></u>
4 + y₂ = 8
y₂ = 8-4 =4
The co-ordinates of point D( 4,4)
