A toy falls from a window 70 feet above the ground. How long does it take the toy to hit the​ ground?
Korolek [52]

Answer:

2.09 seconds.

Step-by-step explanation:

We are given...

y = 70 feet

v0 = 0 feet/second

a = 32 feet/second^2

We need to find t using the following equation...

y = v0 * t + (1/2) * a * t^2

70 = 0 * t + (1/2) * 32 * t^2

70 = (1/2) * 32 * t^2

70 = 16t^2

16t^2 = 70

t^2 = 4.375

t = sqrt(4.375)

t = 2.091650066

So, it will take the toy about 2.09 seconds to hit the ground.

Hope this helps!

Find the volume of a cylinder that has a diameter of 12 in. and a height of 15 in
daser333 [38]

Answer:

<h3>\sf{ \boxed{ \bold{1697.14}}}</h3>

Step-by-step explanation:

Given,

diameter ( d ) = 12 in

height ( h ) = 15 in

<u>finding </u><u>the </u><u>radius </u><u>of </u><u>a </u><u>cylinder</u>

Radius is just half of diameter.

Radius ( r ) = 12 / 2 = 6 in

<u>finding </u><u>the </u><u>volume </u><u>of </u><u>a </u><u>cylinder </u><u>having </u><u>radius </u><u>of </u><u>6</u><u> </u><u>in </u><u>and </u><u>height </u><u>of </u><u>1</u><u>5</u><u> </u><u>in</u>

Volume of a cylinder = <u>\sf{\pi  \:  {r}^{2} h}</u>

⇒\sf{ \frac{22}{7}  \times  {6}^{2}  \times 15}

⇒\sf{ \frac{22}{7}  \times  36 \times 15}

⇒<u>\sf{1697.14} \: in</u>

Hope I helped!

Best regards!!
