Answer:
2968.30 cm cube.
Step-by-step explanation:
Given is a cone and top of it is a hemisphere of radius 9 cm.
Cone has height as 17 and radius same 9 cm.
We have to find the volume of the compound shape
We find that the volume would be the sum of that of hemisphere of radius 9 cm and cone of height 17, and radius 9 cm.
Volume of compound shape = volume of cone+Volume of hemisphere
=
substitute for h and r in the equation
Required volume =
[/tex]
So answer is 2968.30 cm cube.

<em><u>The solution is (4, 4)</u></em>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
<em><u>Substitute eqn 2 in eqn 1</u></em>
Make the right side of equation 0
<em><u>Solve by quadratic equation</u></em>
<em><u>Substitute x = 4 in eqn 2</u></em>
y = 2(4) - 4
y = 8 - 4
y = 4
Thus solution is (4, 4)
Answer:
Step-by-step explanation:
Area is given by the product of length and breadth
Answer:
? ≈ 24°
Step-by-step explanation:
Using the sine ratio in the right triangle
sin? = = , then
? - ( ) ≈ 24° ( to the nearest degree )
Answer:
<h2>The width is 13</h2>
Step-by-step explanation:
From the question
P=2L+2W
where
L is the length
W is the width
To make W the subject move 2L to the left side of the equation
That's
2W = P - 2L
Divide both sides of 2 to make W stand alone
We have
when
P = 70
L = 22
W is
We have the final answer as
<h3>W = 13</h3>
