Step-by-step explanation:

Q3.

The formula of a lateral area of a cube with side s:

We have s = 4.1 ft.

Substitute:

Q4.

The formula of a surface area if a cylinder:

r - radius

H - height

We have 2r = 62 cm → r = 31 cm, H = 85 cm.

Substitute:

Q6.

The surface area of a square piramid is

base - square

lateral sides - four triangles

The formula of an area of a square with sides s:

The formula of an area of a triangle with base b and height h:

We have s = 5 cm, b = s = 5 cm, h = 9 cm.

Substitute:

The surface area:

Q10.

The lateral sides are two pairs of rectangles.

The formula of an area of a rectangle:

l - length

w - width

We have the rectangles:

5 in × 10 in and 7 in × 10 in

Substitute:

The lateral area:

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
