Step-by-step explanation:
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
To round a number to the nearest tenth, we must look at the hundredths place because it is the next number to the right.
In this case, 1 is in the tenths place and 6 is in the hundredths place.
If the number to the right is 0-4, then the number being rounded is rounded down.
If the number to the right is 5-9, the the number being rounded is rounded up.
Since 6 is one of the numbers in the 5-9 list, the number being rounded (1) will be rounded up.
Therefore, 1 will be round to the next whole number which is 2.
This means the number will be 314.2
