Answer:
Step-by-step explanation:
Alright, lets get started.
We first need to find the surface area of the ramp without its base.
The ramp consists 4 sides two triangles and two rectangles.
Area of 1 triangle = 
Area of 2 triangle = 42
Area of top rectangle = 
Area of back rectangle = 
So total area =
square feet
We are asked to paint two coats of paint means we have to double the area.
So the double area is = 
80 square feet requires = 1 quart of paint
994.8 square feet requires = 
12.4 quart can't be purchased so complete number of quart will be 13 quart. : Answer
Hope it will help :)
Answer:
40.5
Step-by-step explanation:
(n-2)*180
(7-2)*180=5*180=900
10p+135+149+121+90=900
10p=-495+900=405
p=40.5
Answer:
radius is 7yd, height is 4 yd, v=3.14 x 7^2 x 4. The last one, I'm not too sure about but it might be V= 615.44^3
Step-by-step explanation:
Recallin that, the diameter is twice as long as the radius, namely the radius is half the diameter, so, if the diameter is doubled, the radius is also doubled.

notice, the new volume is 4 times (πr² h), namely 4 times the original.
