Answer:
1046 pounds
Step-by-step explanation:
The volume of the hemisphere is given by the formula ...
V = 2/3πr³
where r is the radius, or half the diameter.
The radius is (4 ft)/2 = 2 ft, so the volume of the tank is ...
V = (2/3)π(2 ft)³ = 16/3π ft³ ≈ 16.755 ft³
Then the weight of the water in the tank is ...
(16.755 ft³)(62.4 lb/ft³) ≈ 1045.52 lb
The total weight of the water is about 1046 pounds.
If the radius is the radius of the inscribed circle then the side of the triangle = radius * 6 / (sq root(3))side = 20.785tan 60 = height / half-sideheight = tan 60 * half-sideheight = 1.732 * 10.3925 height = 17.99981 triangle area = .5*side*heighttriangle area = 10.3925 * 17.99981triangle area = 187.06
If the radius is the radius of the circumscribed circle then the side of the triangle = radius *3 / (sq root(3))side of the triangle = 6 * 3 / sq root(3)side of the triangle = 10.3923048454 half-side = 5.1961524227 height = tan 60 * half-sideheight = 1.732 * 5.196height = 8.9997
triangle area = .5*side*heighttriangle area = 5.196 * 8.9997triangle area = 46.764
Hope this helps!
The cyclic quadrilateral's opposing angles are 180 degrees, which become supplementary angles.
<h3>What is a cyclic quadrilateral?</h3>
If the quadrilateral is inscribed in a circle then the quadrilateral is known as a cyclic quadrilateral.
A quadrilateral can be inscribed in a circle, if and only if, the opposite angles in that quadrilateral are supplementary.
We know that the sum of the opposite angles of the cyclic quadrilateral is equal to 180 degrees.
Supplementary angle - Two angles are said to be supplementary angles if their sum is 180 degrees.
