Given a Rectangular piece of paper 11cm × 4cm is folded without overlapping to make a cylinder of height 4 cm

The length of the paper becomes the circumference of the base of the cylinder and width becomes height.

Let radius of the cylinder= r and height= h

Circumference of the base of cylinder = 2πr = 11cm

⇒2× 22/7 × r = 11

∴r= 7/4 cm

Now h = 4cm

Volume of the cylinder (V)=πr^2h

= 22/7 × 7/4 × 7/4 × 4cm^3

= 38.5cm

The work in an office takes 150 hours to complete every week. Each person in the office works 32hours a week. What is the smalle

tatiyna

Answer:

Step-by-step explanation:

To answer this, we must figure out the minimum amount we can add 32 to itself to reach 150. This means that we must multiply 32 by our desired amount, x, to reach the amount of hours closest to 150 (but above/equal to it). To find x, we can divide 150 by 32, and if it gives us a number with no decimals or remainders, that is x, as it is the smallest amount of people to get above/equal to 150. If it gives us a remainder/decimal, we must round up, as we cannot have a part of a person and we must get the work done, so we must get at least 150 hours. 150/32 is 4.6 something, so we must round up. 5 is our answer

Three co-workers are packing books in a storage bin. The bin is 4 feet high, 9 feet long, and 11 feet wide. If 6 books fill 1 cu

evablogger [386]

Alright, lets get started.

Height of the bin = 4 ft

Length of the bin = 9 ft

Width of the bin = 11 ft

Volume of the bin = $L*W*H$

Volume V $= 9*11*4$

Volume V $= 396$ cubic feet

6 books fiils 1 cubic feet

1 cubic feet is filled by = 6 books

So, 396 cubic feet is filles by $= 396 * 6$

So, 396 cubic feet is filles by $=2376$ books

It means 2376 books will fit in the storage bin. : Answer

Hope it will help :)

Cylinder A has a radius of 10 inches and a height of 5 inches. Cylinder B has a volume of 750π. What is the percentage change in

Firlakuza [10]

Answer:

50% change in volume

Step-by-step explanation:

<h2>This problem bothers on the mensuration of solid shapes.</h2>

In this problem we are to find the volume of the first cylinder and compare with the second cylinder.

Given data

Volume v = ?

Diameter d= ?

Radius r = $10 in$

Height h= $5 in$

we know that the volume of a cylinder is expressed as

$volume = \pi r^{2}h$

Substituting our given data we have

$volume = \pi*10^{2}*5\\ volume= \pi *100*5\\volume= 500\pi in^{3} \\$

The first cylinder as a volume of $500\pi$

The change in volume is $750\pi - 500\pi = 250\pi$

percentage = $\frac{250\pi }{500\pi } *100$

$percentage=$ $0.5*100= 50$ %

The math club sells candy bars an d drinks during football games. • 60 candy bars and 110 drinks will sell for $265. • 120 candy

Sedbober [7]

We can set up a system of equations to solve this.

120b + 90d = 270
60b + 110d = 265

To cancel out b, first make the b terms equal.

60b · 2 + 110d · 2 = 265 · 2
120b + 220d = 530

Now subtract the equations.

120b + 90d = 270
-120b + 220d = 530
---------------------------
-130d = -260

Solve for d.

-130d/-130 = -260/-130
d = 2

Now put the value of d in one of the equations.

60b + 110d = 265
60b + 110 · 2 = 265
60b + 220 = 265
60b + 220 - 220 = 265 - 220
60b = 45
60b/60 = 45/60
b = 0.75

Each candy bar sells for $0.75

Hope this helps! :)
