Answer:

\boxed{ \rm \: Volume_{(Cylinder)} \approx \: 461.6  \:  {m}^{3} } \rm (rounded \: to \: nearest \: tenth)

Step-by-step explanation:

Given dimensions:

  • Radius of the cylinder = 7 metres
  • Height of the cylinder = 3 metres

Given value of π :

  • π = 3.14

To find:

  • The Volume of the cylinder

Solution:

Here, we'll need to use the formulae of the volume of cylinder,to find it's volume.Its actually like a savior while solving these type of questions.

\pink{\star}\boxed{\rm \: Volume_{(Cylinder)} = \pi{r} {}^{2} h}\pink{\star}

where,

  • π = 3.14
  • r² = (radius)²
  • h = height

Plug/substitute them onto the formulae,then simplify it using PEMDAS.

  • [We'll substitute the value of π later]

\rm \: Volume_{(Cylinder)} = \pi(7) {}^{2}  \times 3

\rm \: Volume_{(Cylinder)} = \pi(49)(3)

\rm \: Volume_{(Cylinder)} = 147\pi \:

  • Now substitute the value of π.

\rm \: Volume_{(Cylinder)} = 147 \times 3.14

\rm \: Volume_{(Cylinder)} = 461.58 \:  {m}^{3}

\boxed{\rm \: Volume_{(Cylinder)} \approx \: 461.6  \:  {m}^{3}} \rm (rounded \: to \: nearest \: tenth) \:

<u>Hence, we can conclude that:</u>

The volume of the cylinder is approximately

461.6 m³.

A square is cut into two congruent triangles by drawing the diagonal between two corners. If the area of each triangle is 162 cm
Pavel [41]
Ok so area=162
since the triangles sides were cut out of a square, base=height
area=1/2bh=162
b=h
area=1/2b^2=162
times 2 both sides
b^2=324
sqrt both sides
b=18=h
the legnth of one side is 18cm
see diagram

another way, is total aera of square=areas of  both triangles=162+162=324
remember area of square=side^2 so
324=side^2
sqrt both sides
18=side

answer is 18cm

HELP ME ASAP WHAT IS THIS ANSWER
ollegr [7]

Answer:

These kind of problems  are super difficult Anna, don't feel bad for not getting this. there is a bunch of "implied" ideas here... i'll go over them below, maybe it will seem a bit easier.  if not, ask some more questions in the comments of this problem , I'll see the comments and answer your question

Step-by-step explanation:

the 1st implied idea is that there is 360 ° in a circle

next you have to know, that the angle x   is also matched on the interior of the circle where the line of the angle x, first touches the circle.  if that is confusing , don't worry i'll make a rough drawing to show you.  

so we can know that the arc from the point where the angle x makes the tanget.. or just touches the circle to where it's other leg crosses the circle the 1st time,  that's angle is equal to the arc that is left over from the total circle.  see this is very "implied"  nobody said.. by the way... it's 360 ° minus the other arcs.. well.. I just did.. but  you had to come up with that on your own, before I said that.

x =  left over arc

360 = 200 + 40 + x

120 = x
