All of them beacause each one of them measured a lenght of a sidewalk
Answer:
Step-by-step explanation:
Part 1: Solve for the total amount of marbles
To solve for the probability of certain events, a population is needed to derive this information from. In order to find this population, add up the amounts of each marble.
8 + 14 + 12 = 34 marbles
Part 2: Determine the probabilities
Now, given the amounts of marbles, simply multiply the ratios of blue marbles to total marbles and the ratio of clear marbles to total marbles to get the combined probability.
The probability of these events occurring simultaneously is 15%.
Answer: The approximate total volume of the silo is 116.5 m3
Step-by-step explanation:
Hi, the volume of the silo is equal to: volume of the cylinder + volume of the hemisphere:
Volume of the cylinder:
V = π x r²x h
Where:
R = radius (in this case, to obtain the radius we have to divide the diameter by two since radius = diameter /2)
h = height
Replacing with the values given:
V = π x r²x h = 3.14 x (4.4/2) ²6.2= 3.14 x (2.2)²x 6.2 = 94.22512 m3
And for the hemisphere:
Volume of the hemisphere: 2/3 x π x r3
Replacing with the values given;
v= 2/3 x 3.14 x 2.2∧3= 22.28m3
Finally, adding both results:
Volume of the silo = volume of the cylinder + volume of the hemisphere:
94.22 m3+ 22.28m3 = 116.5 m3
992,449 rounded to the nearest hundred thousands is 1,000,000.
