Answer:
Step-by-step explanation:
From the picture we find that the sphere and the cylinder has equal heights.
i.e. cylinder has height = 2r.
x,y and r form a right triangle with hypotenuse as r.
Hence pythagorean theorem is satisfied
Area of the cross section parallel to it is area of circle with radius y
=
Volume of cylinder when 2 cones removed =
Hence volume of sphere =

Answer:
<h3>230.65 </h3>Step-by-step explanation:
If two sides are the same (two sides measure 23.66) this means the triangle is an isoceles triangle. The equation for area of an isoceles triangle is as follows:
x base x height.
As you have the size of the base, you need to find the area of the height.
As this turns into a pythagoras' theory question, you need to reacall:
To get the b^2 value we need to divide the total base (22.8) value in two:
22.8 ÷ 2 = 11.4
So, as you have the hypotenuse () and the base (
) we need to find the
value.
To do this we need to subtract the value from the
value:
Plug the values in:
So
Simply square root this to find a:
a = 20.7325
Now we have all the possible value, we need to plug them into the area formula which was:
x base x height
Plug the values in:
= 230.6505
<h3>So the area is 230.65 feet!</h3><h3 /><h2>Hope this helps!</h2>
