The first question’s answer is the last option. And the range is 104
Answer:
a) The diagram shows a hemisphere with radius 6 cm.
Calculate the volume.
Give the units of your answer.
(The volume, V, of s sphere with radius r is V = 4/3πr³)
b). The diagram shows a prism ABCDEF.
The cross-section is a right angled triangle BCD. BD = 10 cm, BC = 5.2 cm and ED = 18 cm.
(i) a) Work out the volume of the Prism.
b) Calculate the angle BEC
c) The point G lies on the line ED and GD = 7 cm. Work out angle BGE

<h3>
ax² + bx + c = 0</h3>
<em>Let's write -9 where we see A</em><em>:</em>
<h3>
-9x² + bx + c = 0</h3>
<em>Let's</em><em> </em><em>write</em><em> </em><em>0</em><em> </em><em>where</em><em> </em><em>we</em><em> </em><em>see</em><em> </em><em>B</em><em>:</em>
<h3>
-9x² + 0.x + c = 0</h3>
<em>(</em><em>Since B = 0, when it is multiplied by x, it becomes 0 again</em><em>)</em>
<h3>
-9x² + c = 0</h3>
<em>Let's</em><em> </em><em>write</em><em> </em><em>-2</em><em> </em><em>where</em><em> </em><em>we</em><em> </em><em>see</em><em> </em><em>C</em><em>:</em>
<h3>
-9x² + -2 = 0</h3>
<em>Now we can move on to solving our equation</em><em>:</em><em>)</em>
<em>Let's put the known and the unknown on different sides:</em>
<em>(</em><em>-2 goes to the opposite side positively</em><em>)</em>
<h3>
-9x² = 2</h3>
<em>(</em><em>i</em><em>t goes as a division because it is in the case of multiplying -9 across</em><em>)</em>

<h3>
x² = 2/-9</h3>

Answer:
the rate at which work is done.
Step-by-step explanation:
I believe that's the answer specifically in physics.
6, 2, 0.(6) and so on
you simply divide each number by 3
