Answer:
d)96π
Step-by-step explanation:
Given:
Cyliner with radius,a= 4
Height b=8
Surface area of cylinder, A=2πrh+2πr^2
=2π(rh+r^2)
=2π(4(8) + 4^2)
= 2π(32+16)
=2π(48)
=96π !
Answer: Option D.
The area of the circular bases is:
Where
is the radius of the circle
Then
The area of the rectangle is:
b is the width of the rectangle and is the length
Then the area of the rectangle is:
Finally the total area is:
D is the answer
The above question answer is (a) leading coefficient is positive and degree is odd.
Hope it is right answer for it!!
