If a plant manufacturing carpet backing has a cylindrical tank that is 3 meters high and is 6 meters in diameter, what is the volume of the tank? Assume 3.14 for pi.

Answers

Answer 1

Answer: Volume of a cylinder = cross sectional area * height
so...
height = 3m
cross sectional area = pi × radius^2
radius = 1/2 diameter
radius = 1/2 × 6 = 3
3.14 × 3^2
= 3.14 × 9
= 28.26
therefore...
volume of cylinder = 28.26 × 3
= 84.78 m^3

Answer 2

Answer: volume = area of base x height
v=pi x radius^2 x height

v=3.14 x 3^2(6/2 because 6 is diameter so must divide by 2 for radius) x 3
v=84.78 m3

12. Snowfall At 8:00 A.M., you measure the depth of snow in your backyard to be4 inches. At 6:00 P.M., you measure the snow depth to be 19 inches. What is the
average rate of change in the snow depth?
10

Answers

Answer: The answer would be 1.5

Step-by-step explanation: From 8-6 it is 10 hours. Then you go from 4 inches to 19 inches. So every 10 hours is 15 inches more of snow. If you divide 15 by 10 then it is 1.5

The floor of a hall has an area of 48 dm.The floor is to be tiled by triangular tiles.of sides 20 cm,30 cm and 40 cm. Find the total cost of tiles if cost of each tile is Rs.200.

Answers

The triangle is an obtuse triangle. No sides are equal.
convert cm to dm

1 dm = 10 cm

side a: 20 cm ⇒ 20cm * 1dm/10cm = 20dm/10 = 2 dm
side b: 30 cm ⇒ 30cm * 1dm/10cm = 30dm/10 = 3 dm
side c: 40 cm ⇒ 40cm * 1dm/10cm = 40dm/10 = 4 dm

We need to get the area of a triangle, but first we need to solve for its height using Heron's formula

s = (a+b+c)/2 = (2+3+4)/2 = 9/2 = 4.5
Area = √(s(s-a)(s-b)(s-c)
h3/2 = √4.5(4.5-2)(4.5-3)(4.5-4)
h3/2 = √4.5(2.5)(1.5)(0.5)
h3/2 = √8.44
h3/2 = 2.91
h = (2.91*2)/3
h = 1.94

A = hb/2 = (1.94*3)/2 = 5.82/2 = 2.91 dm²

48 dm² / 2.91dm² = 16.5 or 17 tiles needed

17 x Rs200 = Rs3,400 is the total cost

There are a total of 100 balloons. If the ratio of yellow balloons to blue balloons is 8 to 12, how many of them are yellow

Answers

If you have 8 yellow balloons for every 12 blue balloons, then if you have 20 balloons in total, 8 out of 20 of those balloons will be yellow. Then you can set up this ratio:

$(8yellow)/(20total) = (Xyellow)/(100total)$

Then, you can use either cross multiplication or multiply the numerator and denominator by the same number to help solve for x. Personally, I prefer cross multiplication, so that's what I'll show you here:

$(8yellow)/(20total) = (Xyellow)/(100total) \n 8yellow*100total=20total*Xyellow$

Finally, solve for x:

$8yellow*100total=20total*Xyellow \n 8*100=20*x \n 800=20x \n 800/20=20x/20 \n x=40yellow$

If you had 100 balloons, you will have 40 yellow balloons.

Hope this helps!!
