A right circular cylindrical metallic rod is 15 inches tall. The radius of the base is 2 inches. What is the surface area of the
Artyom0805 [142]

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

Two pairs of statements about Jeff's housing expenditures are given below. How can both pairs of statements be true?
Irina18 [472]

Explanation:

Pair 1 is true if Jeff's monthly income is $600/20% = $3,000.

Pair 2 is true if Jeff's monthly income is $1200/10% = $12,000.

Both pairs can be true if Jeff's monthly income increased by a factor of 4 in the 20 years from 1990 to 2010.

Obviously, Jeff spent more on housing in 2010. (Fortunately for Jeff, that larger expenditure was a smaller fraction of his income.)
