The circumference of a circle whose radius is 9x sq. is

True [87]

<h3>The circumference of circle is $56.52x^2$ units</h3>

Solution:

Given that,

Radius of circle = $9x^2$ units

To find: circumference of circle

The circumference of circle is given as:

$C = 2 \pi r$

Where, r is the radius of circle

Substitute, r = $9x^2$

$C = 2 \times 3.14 \times (9x^2)\\\\C = 6.28 \times 9x^2\\\\C = 56.52x^2$

Thus circumference of circle is $56.52x^2$ units

Given that y varies directly as x and y = 18 when x = 6

sergey [27]

Answer: y = 15, x = 10

Step-by-step explanation:

NOTE: "varies directly" is of the form $\dfrac{y}{x}=k$ where k is the constant of proportionality.

First, input the given x and y-values to find k

$\dfrac{y}{x}=k\qquad \qquad \text{Given: y=18, x=6}\\\\\dfrac{18}{6}=k\\\\\boxed{3=k}$

Next, input the given value and k = 3 to solve for the missing variable.

$x = 5\\\\\dfrac{y}{5}=3\\\\\large\boxed{y = 15}\\\\\\y=30\\\\\dfrac{30}{x}=3\\\\\dfrac{30}{3}=x\\\\\large\boxed{10 = x}$
