the volume of a cone is 120 cubic centimeters. the height of the cone is 4.5 centimeters. determine the radius of a cone

kolbaska11 [484]

<h3> given:</h3>

$v = 120 \: {cm}^{3}$

$h = 4.5 \: cm$

the radius of the cone.

<h3>solution:</h3>

$r = \sqrt{3 \frac{v}{\pi \: h} }$

$r = \sqrt{3 \times \frac{120}{\pi \times 4.5} }$

$r = 5.04627 \: cm$

$r = 5.05 \: cm$

hence, the radius of the given cone is 5.05 centimeters.

On average, Jaimie can bike five times as fast as he can run. To travel 25 km, he needs 2 h more if he is running than if he is

Answer: Running speed is 10k/h

Biking speed is 50k/h

Step-by-step explanation:

My procedure may be unconventional, but it works:

Compute the time it takes, then translate to speed. 25k at biking speed takes 2 hours less than at running speed which is 1/5 bike speed.

Distance/speed = time 25/x=25/(5x-2) cross multiply divisors

25(5x-2) = 25x ==> 125x -50 =25x ==> 100x = 50

x = 0.5 hours at biking speed 25k/0.5h = 50k/h

Running speed = 50/5 10k/h

Proof: 25k/ 10k/h = 2.5 hours

25k /50k/h = 0.5 hours

2.5 h - .5 h = 2 hours, the difference stated in the question.
