Mathematics
1 answer:
fiasKO [112]3 years ago
4 0

Answer: C

Step-by-step explanation:

Formula: V=\pi r^2h

We do not have the radius, but we do have the diameter. A diameter is twice the radius, therefore we can divide the diameter by 2 in order to obtain the radius.

\frac{d}{2}=\frac{12}{2}  =6

Plug this info into the formula.

V=\pi r^2h\\V=\pi (6)^2(7)\\V=\pi 36*7\\V=252\pi in^3

Which teacher exhibited the most variable year to year performance over this 5 year span?
Tanzania [10]

<u>Answer-</u>

Ed exhibited the most variable year to year performance over this 5 year span.

<u>Solution-</u>

Most variable performance means varying performance or non-consistence performance.

As shown in the graph,

Jill's performance was constant throughout 2005-07.

Ralph's performance was constant throughout 2006-07 and also in 2008-09.

Tina's performance was constant throughout 2007-09

Sam's performance was constant throughout 2008-09.

All of them has been consistence for at-least once. But, in case of Ed, throughout the time, his performance was in-consistence or variable.

A shop keeper sells an article for 400

He purchases it for 402.

Therefore, loss = cost price - selling price

402 - 400 = 2

% loss =

loss/cost price x 100%

2/402 x 100%

= 200/402

=0.498

=0.5%

Find the perimeter of the polygon with the given vertices. C(4, -1), D(4,−5), E(2,−3)
Aleksandr [31]

Answer:

8 units

Step-by-step explanation:

find the distance of the lines through coordinates given

distance formula: \sqrt{(x_{1}-x_{2})+(y_{1} -y_{2} )  }

i) CD=\sqrt{(4-4)^2 +(-1+5)^2}

  CD=\sqrt{0+4^2}

  CD=4 units

ii) DE=\sqrt{(4-2)^{2}+(-5+3)^2 }

 DE=\sqrt{(2)^2+(-2)^2}

 DE=\sqrt{8}

 DE= 2 units

iii) ED=\sqrt{(2-4)^2+(-3+1)^2}

   ED=\sqrt{(-2)^2+(-2)^2}

   ED=\sqrt{8}

   ED= 2 units

perimeter of polygon= 2 units+ 2 units+ 4 units

                                  =8 units

The wheels on Karen’s rollerblades each have a diameter of 5 cm. How far will the rollerblade travel in one turn of the wheel? U
Ierofanga [76]
To find the distance in one turn of the wheel you have to find the circumference of the wheel.

Circumference = pi x d
= 3.14 x 5
= 15.7 cm

therefore the rollerblade wheel will travel 15.7 cm per rotation

hope this helps! if you did not understand a step or concept please let me know!
