Answer:
40 inches
Step-by-step explanation:
Volume, V of hemisphere = 2/3 π r^3
Radius, r = 24 inches ;
V = 2/3 π 24^3
V = 28952.917 in³
Volume of cylinder = π r^2 * h
h = height ; r = Radius = 32 /2 = 16 inches
Volume of hemisphere = volume of cylindrical tank
28952.917 = π (16)^2 * h
28952.917 = 804.24771h
h = 28952.917 / 804.24771
h = 35.9999
h = 40 inches
Molten stell rise is 40 inches
Its average speed rounded to 1dp is 54.76 miles per hour.
<h3>Average speed</h3>
Using this formula
Average speed=Distance/Time
Where:
Total Distance =230 miles
Time= 4.2 hours
Let plug in the formula
Average speed=230/4.2
Average speed=54.76
Inconclusion Its average speed rounded to 1dp is 54.76 miles per hour.

The equation that could be used to solve for the length of XY is XY = 22/sin(41)
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
Sine rule is used to show the relationship between the sides and angles of a trinagles.
Using sine rule on triangle XYZ:
XY / sin(Z) = XZ / sin(Y)
XY / sin(90) = 22/sin(41)
XY = 22/sin(41)
The equation that could be used to solve for the length of XY is XY = 22/sin(41)
