Dale and sharon mahnke have decided to fence off the garden plot behind their​ house, using their house as a​ "fence" along one
kkurt [141]

The length l is given as:

l = 2 w – 6

where w is the width

 

We know that the fencing is 30 feet therefore the perimeter (excluding the side of the house) is:

P = l + 2 w = 30

2 w – 6 + 2 w = 30

4 w – 6 = 30

w = 9

 

So the length l is:

l = 2 (9) – 6

l = 12

The surface area, A, of a cylinder is given by the formula A = 2 Trh + 2nr, where ris the radius and h is the height
lord [1]

Answer:

Area = 87.9646  sq. units  from A = 28*π  sq. units.

However I cannot see this in your answer list, since the numbers look all jumbled.  Choice A. looks close to it, since there is a 28...

Step-by-step explanation:

We have a cylinder with height h = 5

radius = 2

We want the surface area of this cylinder.

A = (circumference)*h  + 2*(pi)*r^2

A = ( 4*π)*5   + 2*π*(2^2)

A = 20π + 8π  =  28 π   square units

A = 87.9646 sq.. units
