Square root (5-2)^2 +(4+3)^2
Square root of 3^2 +7^2
Square root of 9+49
Square root of 58
We know that
density=mass/volume
solve for mass
mass=density*volume
step 1
find the area of the garage door in cm²<span>
Area=300*700------> 210000 cm</span>²
step 2
find the volume of the paint
Volume=area*thick
thick=1 mm-----> 0.1 cm
Volume=210000*0.1-----> 21000 cm³
step 3
find the mass
mass=density*volume
density=1.2 g/cm³
volume=21000 cm³
mass=1.2*21000-----> 25200 grams
the answer is
25200 grams
The width is basically the diameter:
Given
Diameter = 5.5 cm
So Radius =

=

= 2.75 cm
Height of cylinder = 12.5 cm
Formula of the volume of a cylinder
V = Area of base × height of prism
=

r² × h
=(2.75)² (

) × 12.5
=7.5625

× 12.5
≈ 296.83 cm³
