Step-by-step explanation:
Answer:
=176 pi units^2
Step-by-step explanation:
The surface area of a cylinder is given by
SA = 2 pi r^2 + 2 pi rh where r is the radius and h is the height
= 2 * pi * 8^2 + 2 pi *8*3
= 128pi + 48 pi
=176 pi units^2
Answer:
the second answer is correct
Step-by-step explanation:
an inscribed angle is half of the intercepted arc
Let the side length of each of the squares cut out be x inches.
The volume of the box will be:-
V = x(19 - 2x)(11 - 2x)
V = x( 209 - 38x - 22x + 4x^2)
V = x(209 - 60x + 4x^2)
V = 209x - 60x^2 + 4x^3
For maximum/minimum volume we find the derivative and equate to zero:-
dV/dx = 209 - 120x + 12x^2 = 0
solving for x:-
x = 7.75 , 2.25
For maximum volume evaluate the second derivative:-
d^2V/dx^2 = 24x - 120
for x = 2.25 second derivative = 24(2.25) - 120 = -66 so x = 2.25 gives a maximum volume.
Answe:- r the dimensions of the squares is 2.25 * 2.2.5 inches
