Answer: Surface area = 68π inches²
Step-by-step explanation:
The formula for determining the total surface area of the circular cylindrical metallic rod is expressed as
Total surface area = 2πr² + 2πrh
Where
r represents the radius of the cylindrical rod.
h represents the height of the cylindrical rod.
π is a constant whose value is 3.14
From the information given,
Radius = 2 inches
Height = 15 inches
Therefore,
Surface area = (2 × π × 2²) + 2 × π × 2 × 15) = 8π + 60π
Surface area = 68π inches²
Answer:
its 45 as3*15 is 45 and 45*1 is 45
plz mark me branliest
Answer:
Step-by-step explanation:
To solve this, we are using the average rate of change formula:
where
is the average rate of change
is the first point
is the second point
is the function evaluated at the first point
is the function evaluated at the second point
We want to know the average rate of change of the function form x = -3 to x = 0, so our first point is -3 and our second point is 0. In other words, and .
Replacing values
We can conclude that the average rate of change of the exponential equation form x = -3 to x = 0 is
I'm not sure about the first question.
Did you post the question correctly?
Answer:
12 boys
Step-by-step explanation:
- Set up a proportion:
- Cross multiply, then divide: 3 × 16 = 48, 48 ÷ 4 = 12
I hope this helps!
