write an expression to represent the surface area of a cylinder with a height twice as long as its radius​

area = 2 π r 2 + 2 π r h

Step-by-step explanation:

The two circles that make up the ends of the cylinder.

The side of the cylinder, which when "unrolled" is a rectangle

π  is Pi, approximately 3.142

r  is the radius of the cylinder

h  height of the cylinder

The two circles that make up the ends of the cylinder.

The side of the cylinder, which when "unrolled" is a rectangle

Pi (π) approximately 3.142

radius (r) of the cylinder

the height (h) of the cylinder

therefore your answer is

area = 2 π r 2 + 2 π r h

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
