The area is a function of the apex angle β according to
Area = (1/2)(2 cm)²×sin(β)
This will be a maximum for β = 90°. The corresponding length of the third side is
2√2 cm
≈ 2.2828 cm
Y=2/3x+10 - use slope intercept form
Answer:
Dimension
Height =29.01
Breadth=38.70
Step-by-step explanation:
Printed area is =386 and margins as specified.
For printed area let height be x and breadth be y.
x*y=386 ⇒ y = 
Now considering the margins
Height = x+6+6=x+12
Weidth =
+8 +8=
+ 16
Area of poster to be minimised =(x+12)(
+ 16)
Differentiate above area with respect to x and equate to zero to find extrema.
= 16 -
=0
x=17.01
Now plug value of x in height and breadth
Height =29.01
Breadth=38.70
Answer:
43988ft^3
Step-by-step explanation:
Given data
Radius= 20ft
Height= 35ft
The expression for the volume of a cylinder is given as
Volume= πr^2h
substitute
Volume= 3.142*20^2*35
Volume= 3.142*400*35
Volume= 43988ft^3
Hence the volume is 43988ft^3
