Answer:
<h2>A) 3 cm</h2>
Step-by-step explanation:
The formula of a volume of a cylinder:
r - radius
H - height
We have r = 1cm and H = 21cm. Substitute:
The formula of a cone:
r - radius
H - height
We have V = 21π cm³ and H = 7cm. Substitute:
<em>divide both sides by π</em>
<em>divide both sides by 7</em>
<em>multiply both sides by 3</em>
Answer:
x = 3.5y
Step-by-step explanation:
Simplifying
3x + 8y + -5x + -1y = 0
Reorder the terms:
3x + -5x + 8y + -1y = 0
Combine like terms: 3x + -5x = -2x
-2x + 8y + -1y = 0
Combine like terms: 8y + -1y = 7y
-2x + 7y = 0
Solving
-2x + 7y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-7y' to each side of the equation.
-2x + 7y + -7y = 0 + -7y
Combine like terms: 7y + -7y = 0
-2x + 0 = 0 + -7y
-2x = 0 + -7y
Remove the zero:
-2x = -7y
Divide each side by '-2'.
x = 3.5y
Simplifying
x = 3.5y
I think its 91.
NOT Guaranteed this is the Answer. Best of luck to you.
There could be 2 possible shapes that could’ve been drawn.
A rectangle, or a square.
All of their angles are 90° angles, which are right angles.
Hope this helped!
There has to be more to the question so we can show the work. What was the question? :)
