Answer:
Step-by-step explanation:
The pillow is cylindrical. To determine the amount of fabric needed for the pillow, we would apply the formula for determining the total surface area of a cylinder which is expressed as
Total surface area = 2πr² + 2πrh
Where
r represents the radius of the cylinder.
h represents the height of the cylinder.
π is a constant whose value is 3.14
From the information given,
radius = 5 inches
Height = 18 inches
Therefore,
Area = (2 × 3.14 × 5²) + 2 × 3.14 × 5 × 18
Area = 157 + 565.2 = 722.2
Amount of fabric needed is
722.2 square inches
Answer:
As a column vector 3a +b = (9,10)
Step-by-step explanation:
A =
(2
4)
b =
(3
-2)
3a = 3*2 = 6
3*4= 12
3a + b = 6. + 3
12. +(-2)
3a +b = 9
10
As a column vector 3a +b = (9,10)
