Answer:
Step-by-step explanation:
d = diameter = 12ft
r = d/2 = 12/2 = 6ft
Slant height = 13ft
Surface area of cone = π r 2 + π L r
Where L is the slant height of the cone π = 22/7
SA = 22/7×6×6+22/7×13×6
SA = 113.14+245.142
SA = 358.28ft^2
If one bundle of shingle covers 32 ft.²
Hence,358.28ft^2 = 358.28ft^2/32 ft.²
= 11.196
= 11.2 bundles
To write the equation of a line use the point slope formula . Find m by using the slope formula with the points.
Since the line is parallel, it will have the same slope.
Substitute m = -1/3 and (-3,-4).
take 55 degree as reference angle
using tan rule
tan 55=opposite/adjacent
1.42=37/x
x=37/1.42
x=26.05
560 cubes
Volume of prism: lwh, 7*4*2.5, 70cm!
Volume of cubes: lwh, 0.5*0.5*0.5, 0.125cm!
70cm/0.125cm=560 cubes.

rise / run = slope
rise = 2
run = 1
2/1 = 2
slope = 2
