10. Workpad Answer: cost of operating AC at smaller warehouse = $ 125.00 per day.

larger warehouse is 2.5 times larger w r t length , width & height of smaller one.

volume of smaller warehouse = l*w*h cubic units

volume of larger one = 2.5*2.5*2.5 * l*w*h

= 15.625 l*b*h

so, larger ware house occupies 15.625 times space as smaller one.

its cost of operation will be 15.625 times more than the smaller one.

so cost / day = 15.625 * $ 125

= $ 1953.125

= $ 1953.00 [rounded off to nearest dollar]

Hope this helps loves!!

Answer 2

Question 5:
the circumference is given by:
C = 2 * pi * r
Where,
r: radio of the ball
Substituting values we have:
22 = 2 * pi * r
Clearing r we have:
r = 11 / pi
The surface area is given by:
A = 4 * pi * r ^ 2
Substituting values we have:
A = 4 * 3.14 * (11 / 3.14) ^ 2
A = 154 in ^ 2
Answer:
The surface area of the balloon is:
A = 154 in ^ 2

Question 8:
For this case we have that the scale factor is given by:
V1 = (k ^ 3) * V2
Substituting values we have:
729 = (k ^ 3) * 2744
Clearing k:
k = (729/2744) ^ (1/3)
k = 9/14
Answer:
the scale factor of a cube with volume 729 m ^ 3 to a cube with volume 2,744 m ^ 3 is:
9:14

Question 2:
The volume of the cylinder is given by:
V = pi * r ^ 2 * h
Where,
r : radio
h: height
Substituting values:
V = pi * (2.8) ^ 2 * (13)
V = 101.92 * pi
Answer:
The volume of the cylinder is:
V = 101.92 * pi
