Answer:

2010.62

Step-by-step explanation:

the formula to find a cylinders volume is r and h so you just divide 14 and get 8, then you get the 10 and you solve for how you would usually get your cylinder volume. which is V=πr2h=π·82·10≈2010.62

Answer:

V=1539.38

Step-by-step explanation:

V=πr2h=π·7^2·10≈1539.3804

or if you just want shortened version

V=π·7^2·10≈1539.3804

hope this helps!

Answer:

80°

Step-by-step explanation:

The sum of the two angles (red and blue) is 145°, so you have ...

(4x +5)° +(6x -10)° = 145°

10x = 150 . . . . . . . . divide by °, add 5, simplify

x = 15 . . . . . . . . . . . divide by 10

Then the measure of the angle of interest is ...

m∠XMN = (6x -10)° = (6·15 -10)° = 80°

Given that y is directly proportional to x^2 and that y=2 when x=3 find the value of y when x=6

Sergio039 [100]

Answer:y=4/3

y is directly proportional to x^2 is written as

$y \alpha {x}^{2}$ introducing a constant,

y=kx^2

but from the question, when y=2 , x=3 . putting it in the formula to get the value of k

$2 = {3}^{2} \times k$

2=9k . dividing through by 9 to get the value of k

 $\frac{2}{9} = \frac{9k}{9}$ 

 $k = \frac{2}{9}$ 

putting it in the general expression

 $y = \frac{2}{9} x$ 

the value of y when x=6

 $y = \frac{2}{9} \times 6$ 

 $y = \frac{4}{3}$ 

therefore the value of y when x=6 is

4/3
