Find the radius of the cylinder when volume is 304 cm^3 and height is 10 cm

aleksandr82 [10.1K]

Answer:

solution,

Volume of cylinder=304 cm^3

height=10 cm

Radius=?

Now,

$volume = \pi {r}^{2} h \\ or \: 304 = 3.14 \times {r}^{2} \times 10 \\ or \: 304 = 31.4 \times {r}^{2} \\ or \: {r}^{2} = \frac{304}{31.4} \\ or \: {r}^{2} = 9.68 \\ or \: r = \sqrt{9.68} \\ or \: r = \sqrt{ {(3.11)}^{2} } \\ r = 3.11 \: cm$

Hope this helps..

Good luck on your assignment..

What is the probability of picking a blue coin out of a bag that contains 5 blue and 10 red coins

Neko [114]

the probability is 5/15 or 1/3.

You add up all the coins (5+10=15) and since there’s 5 blue coins in the bag, you put 5 over 15. You simplify that to 1/3.

hope this helped !!
