* PLEASE ANSWER DIFFICULT QUESTION * Which formula is correct in computing 50% of the volume of the shape below?

B

Step-by-step explanation:

volume of a cylinder:  V=πr^2h

so for 1/2 volume we can just multiply by 1/2

so

V = 1/2 (πr^2h)

plug in values r = 4.6 and h = 12.4

V= 1/2 π (4.6)^2 (12.4)

so the answer is B

so the answer is B

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%
