Step-by-step explanation:
Answer:
64y² - 81
Step-by-step explanation:
(8y +9)(8y - 9)
64y² - 72y + 72y - 81
64y² - 81
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
6 and 5.
6 is one more than 5, and 5 * 6 = 30.
Hope this helps! Have a great day :)
