Answer:

14.32 inches to nearest thousandth.

Step-by-step explanation:

Circumference = π * d where d = the diameter.

So 45 = π * d

d = 45 / π

= 14.32 inches

Answer:

diameter ≈ 14.32 in ( 2 dec. places )

Step-by-step explanation:

the formula for calculating the circumference (C) of a circle is

C = πd ← d is the diameter

isolate d by dividing both sides by π

d = $\frac{C}{\pi }$ = $\frac{45}{\pi }$ ≈ 14.32

Find the value of x 6x + 12 3x - 3

Shalnov [3]

Answer:

19°

Step-by-step explanation:

Concept Used :-

The measure of a straight line is 180°. So the sum of angles on a straight line is 180° .

Using this ,

$\bf\implies 6x + 12 + 3x - 3 = 180\\\\\bf\implies 9x + 9 = 180\\\\\bf\implies 9x = 180-9 \\\\\bf\implies x =\dfrac{171}{9} \\\\\bf\implies\boxed{\red{\bf x = 19 }}$

<h3>Hence the value of x is 19°</h3>
