Answer:
No Solution
Step-by-step explanation:
all the ordered pair doesn't satisfy the equation.
Draw a perpendicular from the center of the
circle to the midpoint of a side of the triangle.
Now draw a line from the center to the vertex
of that side. You now have a right triangle with
a base angle of 30º, side adjacent to that angle
of 3, and hypotenuse = r, the radius of circle. So,
cos 30º = 3/r, r = 3.46, the diameter
is twice that, 6.92 round to 6.9
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
7/20 is equal to 0.35 or can also be equal to 35% of the whole.
