Answer:
The zeros are 6,-5,9
Step-by-step explanation:
The factored form of the polynomial is given as:
To find the zeros of this function, we set f(x)=0 and solve for x.
This implies that:
We solve for x to get:
The zeros are 6,-5,9

Answer:
350.82
Step-by-step explanation:
To find the surface area, you must add up all of the areas of each shape of the prism in order to get the sum surface area.
The rectangle's area ():
The triangle's area ():
Now add up all the sides. (3 Rectangles, 2 Triangles.)
The total surface area is 350.82 cm squared.
Surface area of the cylinder = 816.4 sq. ft.
Solution:
Height of the cylinder = 21 ft
Diameter of the cylinder = 10 ft
Radius of the cylinder = 10 ÷ 2 = 5 ft
Use the value of = 3.14
Surface area of the cylinder =
Substitute the given values in the surface area formula, we get
Surface area of the cylinder
ft²
Hence the surface area of the cylinder is 816.4 sq. ft.
