<h3>Answer:  326.56 square cm</h3>

==============================================

Work Shown:

SA = 2*pi*r^2 + 2*pi*r*h

SA = 2*3.14*(4)^2 + 2*3.14*4*9

SA = 326.56

Notes:

  • The answer is approximate. Use more decimal digits of pi to get a more accurate answer (though it will never be exact unless you leave it in terms of pi).
  • The portion 2pi*r^2 is the fact we have two circular bases with area of pi*r^2 each.
  • The portion 2*pi*r*h is the lateral area, or the area around the curved side. If you unfold this portion, as you would maybe a label on a soup can, it has base of 2*pi*r and height h. The base 2pi*r is the circumference of the circle of radius r.

The perimeter of a rectangular carton is 60 inches. If the width of the carton is 11 inches, calculate its length
Thepotemich [5.8K]

Answer:

19 inche

Step-by-step explanation:

Perimerer of rectangle = 2(length + breadth)

60 = 2(length + 11)

60/2 = (length + 11)

30 - 11 = length

19 = length

L(t)=9-0.5t   
t=time in hours,
L(t)=length of candle at time t

(A) substitute t=1,2,3,4,5,6 respectively to get
(1,8.5)
(2,8)
(3,7.5)
(4,7)
(5,6.5)
(6,6)

(B) it is a function because none of the x-values duplicate, (nor the y-values).

(C) If the rate changes to 0.45 "/hr, the relation is still linear.
All linear function with finite slope are functions.
