Answer:

Volume of new cylinder = 25446.9 mm³.

Step-by-step explanation:

Given : A cylinder has a height of 1.2 cm and radius = 5 mm.

To find : If all the dimensions of the cylinder are tripled, what will be its new volume.

Solution : We have given that

Height of cylinder = 1.2 * 10 = 12 mm.

radius = 5 mm.

Volume of cylinder = pi * radius² * height.

Volume of cylinder = 3.14 * (5)² * 12

Volume of cylinder = 942.48 mm³.

If the dimensions are tripled

Height = 12 *3 = 36 mm

Radius = 5 * 3 = 15 mm

Volume = pi * radius² * height.

Volume = 3.14 * (15)² * 36

Volume of new cylinder = 25446.9 mm³.

Therefore, Volume of new cylinder = 25446.9 mm³.

An electric bulb is sold in a box measuring 5 cm by 4 cm by 4 cm. If the shopkeeper receives them in a carton measuring 50 cm by

katen-ka-za [31]

Answer:

250

Step-by-step explanation:

Bulb box and carton both are of cuboidal shape.

For bulb box the dimensions are:

l = 5 cm, w = 4 cm, h = 4 cm

$V_{Bulb\: box} =lwh$

$\implies V_{Bulb\: box} =5(4)(4)$

$\implies V_{Bulb\: box} =80\: cm^3$

For Carton the dimensions are:

l = 50 cm, w = 20 cm, h = 20 cm

$V_{Carton} =lwh$

$\implies V_{Carton} =50(20)(20)$

$\implies V_{Bulb\: box} =20,000\: cm^3$

To find the number of bulbs packed in the carton, divide the $V_{Carton}$ by $V_{Bulb\: box}$

$Number \:of \:bulbs =\frac{V_{Carton}}{V_{Bulb\: box}}$

$\implies Number \:of \:bulbs =\frac{20,000}{80}$

$\implies Number \:of \:bulbs = 250$

So, 250 bulbs will be packed in one carton.

What’s the answer and give an explanation.

tino4ka555 [31]

Answer:

14 = x and 2.5 = y

Step-by-step explanation:

For ABCD - the top is 8 and the sides are 11. 11 minus 8 is 3. 11 plus 3 equals 14, that’s x.

For GHIJ - the bottom is 8 and both sides are 5.5. So 8 minus 5.5 is 2.5. That’s y.

WHAT ARE THE SPECIFIC RULES FOR PROVING SIMILARITY IN TRIANGLES? EXPLAIN.

weeeeeb [17]

Answer:

AAA (Or even just two angles work too, since the last has to be the same no matter what) ASA and SSS

Step-by-step explanation:

I believe this is the same as before? As far as I know these are the main rules for proving similarity. (AAS and A** do not exist (Brainly won't let me say the two Ss), make sure no trick questions get you ;p)

I'm not sure if what you needed earlier was the relationships between angles to find them? Like to find Exterior Angles subtract <C from 180 = <EA?
