could 7.2 inches and 28 inches be the diameter and circumference of the same circle? Explain why or why not.
Minchanka [31]

Answer: The diameter 7.2 inches and circumference 28 inches of the same circle could not possible.


Step-by-step explanation: Given diameter of the circle = 7.2 inches.

Circumference of the circle = 28 inches.

Formula for Circumference of the circle = πd, where d is the diameter of the circle.

Plugging value of d in formula, we get

Circumference of the circle = π(7.2).

Plugging π= 3.14, we get

Circumference = 3.14 (7.2) = 22.61.

22.61 is smaller than given circumference 28 inches.

<h3>Therefore, the diameter 7.2 inches and circumference 28 inches of the same circle could not possible.</h3>

During a storm, why do you see the flash of lightning before you hear the roar of thunder? What would it mean if you saw the fla
Lubov Fominskaja [6]
The speed of light is faster than the speed of sound. So that's why you see a flash of lightning before the roar of thunder. If you heard it at the same time as you saw it, well I will be praying for you. It would literally be exactly where you are. If you hear the thunder a long time after the flash, it means the lightning is far away.

T/5=miles away when T is time from the strike of lightning to hearing thunder

A store rents bicycles for $8 per hour. The cost to rent a helmet is $4. How much money does it cost to rent 1 bicycle and 1 hel
shtirl [24]

Answer:

$36

Step-by-step explanation:

The store rents Bicycle and Helmet.

For every 1 hour, a customer pays the following:

Bicycle:

$8 for every ONE HOUR

For THREE HOURS, the cost would be:

$8 * 3hours = $24

(The store rents the BICYCLE at $24 for every three hours.)

Helmet:

$4 for every ONE HOUR

For THREE HOURS, the cost would be:

$4 * 3hours = $12

(The store rents the HELMET at $12 for every three hours.)

COST FOR BOTH BICYCLE and HELMET for three hours

= $24 + $12

= $36
