The circumference (C) of a circle is 16 cm.

Circumference C = \pi *d

The approximate value of \pi is 3.14

Given C = 16

We plug in 16 for C and 3.14 for \pi in the formula C = \pi *d . then solve for d

C = \pi *d

16 = 3.14 * d

'd' is multiplied with 3.14. To get 'd' alone we divide by 3.14 from both sides

\frac{16}{3.14} = \frac{\pi*d}{3.14}

5.09554 = d

So diameter of the circle = 5.1 cm

Drag each expression to show whether it is equivalent to 3 time times 9 or to 2x3x9​
horrorfan [7]

Answer:

The answers to your questions are given below

Step-by-step explanation:

A. 3 × 9 = 27

B. 2 × 3 × 9 = 54

Next, we shall determine which option will give the same result obtained above.

9 × 3 = 27

9 × 3 × 2 = 54

3 × (4 + 5) = 3 × 9 = 27

(2 × 3) × 9 = 6 × 9 = 54

Therefore,

3 × 9 = 27

9 × 3 = 27

3 × (4 + 5) = 27

2 × 3 × 9 = 54

9 × 3 × 2 = 54

(2 × 3) × 9 = 54

SUMMARY

3 × 9 >>>>>>>>> 2 × 3 × 9

9 × 3 >>>>>>>>> 9 × 3 × 2

3 × (4 + 5) >>>>> (2 × 3) × 9

Mike is cycling from the library to his home. The equation shows Mike's distance (y), in miles, from his home after x minutes: y

"12" represents Mike's original distance from his home.  As he rides, this distance decreases by 2 miles/minute  (which is rather unlikely, as that'd be 120 mph).
