Answer:
Step-by-step explanation:
Follow the order of operation: PEMDAS
Parenthesis
Exponents (and roots)
Multiply
Divide
Add
Subtract
3 x (7-2) + 4
first do Parenthesis (as it shows up first)
7 - 2 = 5
Next, Multiply (the next one you have to do)
5 x 3 = 15
Finally, add
15 + 4 = 19
B. 19 is your answer
hope this helps
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
Answer:
≈83.33%
Step-by-step explanation:
400/480 = 5/6
56 * 100 = ≈83.33%
