Answer:

47.1: 50.24

Step-by-step explanation:

V= πr²(h/3)

= 3.14 x 3²(5/3)

= 3.14 x 9(5/3)

= 3.14 x 3(5)

= 3.14 x 15= 47.1

Volume of cylinder

V = πr²h

V = 3.14 x 2² x 4 = 3.14 x 4 x 4 = 3.14 x 16 = 50.24

the ratio of Volume of Cone to Cylinder

47.1: 50.24 = 47.1/50.24 =

Solve the equation for x. 1 6 (2x − 12x) = 30 A) −12 B) −15 C) −18 D) −24

lubasha [3.4K]

$\frac{1}{6}$ *(2x-12x) = 30

$\frac{1}{6}$ *(-10x) = 30

$\frac{-10}{6}$ x = 30

$\frac{-5}{3}$ x = 30

$\frac{5}{3}$ x = -30

x = -30/ $\frac{5}{3}$ = -30 * $\frac{3}{5}$

x = -18

the correct answer is C

Solve for the indicated variable.

Answer:

Option (c) " $r=\dfrac{q}{4c}-h$ "

Step-by-step explanation:

The given equation is :

q = c4(h + r)

We need to solve it for r.

Dividing both sides of the given equation by 4c.

$\dfrac{q}{4c}=\dfrac{4c}{4c}(h+r)\\\\(h+r)=\dfrac{q}{4c}$

Now, subtract h both sides of the equation.

$h+r-h=\dfrac{q}{4c}-h\\\\r=\dfrac{q}{4c}-h$

Hence, this is the required solution.
