Answer:
A
Step-by-step explanation:
The area (A) of a triangle is calculated using the formula
A = bh ( b is the base and h the perpendicular height )
here b = 14 and h = 4, hence
A = (14 × 4) = 28
Compare the function f(x) = 5x + 2 to a function g(x) that contains the following points: (1, -5) (2, -2) (3, 1) ( 4, 4). What i

Lateral Area of cone=1130.4 inches^2
Step-by-step explanation:
Diameter of circular base = 18 inches
Height of cone = 40 inches
Lateral Area of cone = ?
The formula used to find Lateral Area of cone is:
Since we know that r= d/2,
so, r = 18/2
r= 9
Putting values, we get:
So, Lateral Area of cone=1130.4 inches^2

Step-by-step explanation:
Draw a dotted line from b to e
as I've done
you will realize that abfe is a rectangle ,and bced is a trapezium
Area of abfe
=LW
=13ft(10ft)
=130ft^2
Area of bced
=1/2(sum of // sides )height
=1/2(eb+cd)h
h=16ft-10ft
h=6ft
A=1/2(13ft+6ft)×6ft
=19ft(3ft)
=57ft^2
Total areal =(57+130)ft^2
=187ft^2
