Bob bought a solid rubber doorstop to keep the air flowing between the rooms of his apartment.

What is the minimum amount of rubber used to make the doorstop?

33 cm²

Step-by-step explanation:

Area of triangular prism: A = ((1.5 x 2) /2) x 2 + 5 x 2.5 + 5 x 2 + 5 x 1.5

A = 3 + 12.5 + 10 + 7.5 = 33

it is x=-4

step-by-step explanation:

arc length = 6.63311 ft.

step-by-step explanation:

the formula the arc measure is:

arc length s=2πr(c)/360

where:

c   is the central angle of the arc in degrees

r   is the radius of the arc

π   is pi, approximately 3.142

using the above formula we get

s =

thus we find that arc length of an arc for a circle of radius 20 feet and central angle 19 degrees is

6.63311 feet
