(A) 13.75=3p+4h
(B) 9.75=2p+3h

(Ax3) 41.25=9p+12h
(Bx4) 39=8p+12h

(A-B)
2.25=p

So one slice is £2.25

The volume of a metal cylindrical rod is 126 cubic meters. ​The radius is 6 m. ​ ​What is the height of the rod in millimeters?
Dahasolnce [82]

Answer:

1.11 mm

Step-by-step explanation:

The height of a cylinder can be found using the formula: h=V/(πr^2)

This formula was found by taking the formula for the volume of a cylinder and solving for h, or height. Knowing that V is 126 and the radius is 6, we can plug in our known variables in order to solve for h.

A cylindrical Is half full of oil The cylinder Has a base radius of 100 cm The height of the cylinder 250cm 1 litres = 1000cm3 H
Softa [21]

Answer:

V=3926.99 liters

Step-by-step explanation:

cylindrical Is half full of oil The cylinder Has a base radius of 100 cm The height of the cylinder 250cm 1 litres = 1000cm3 How many litres of oil are in the tank?

Volume of a cylinder can be calculated using below formula

V=π r^2 h

Where r= radius

h= height

radius = 100 cm

h=250cm

But the cylinder is half filled, then the formula becomes

V=(π r^2 h) × 1/2

Then substitute the values we have

V=( π × 100^2 ×250) × 1/2

V=3926990 cm^3

But 1 litres = 1000cm3

Then V=(3926990 cm^3)/ 1000

V=3926.99 liters

Help me with this... ​
marin [14]

i. 171

ii. 162

iii. 297

Solution,

n(U)= 630

n(I)= 333

n(T)= 168

i. Let n(I intersection T ) be X

333 - x + x + 468 - x = 630 \\ or \: 333 + 468 - x = 630 \\ or \: 801 - x = 630 \\ or \:  - x = 630 - 801 \\ or \:  - x =  - 171 \\ x = 171

<h3>ii.n(only I)= n(I) - n(I intersection T)</h3><h3> = 333 - 171</h3><h3> = 162</h3>

<h3>iii. n ( only T)= n( T) - n( I intersection T)</h3><h3> = 468 - 171</h3><h3> = 297</h3>

<h3>Venn- diagram is shown in the attached picture.</h3>

Hope this helps...

Good luck on your assignment...
