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:
8
Step-by-step explanation:
Isn't it simple because all other numbers are less than 4?
So 3/5 of 20 is what
'of' means multiply
3/5 of 20 means
3/5 times 20/1=(3*20)/(5*1)=60/5=12/1=12
