Answer:
The value of the variable c is 10cm
Step-by-step explanation:
In this question, we are asked to find the value of the variable C.
From the diagram, we can see that we have the radius of the cylinder and the height of the cylinder.
Now, looking at what we are to calculate, we can see that we have a right-angled triangle, with the height and diameter( 2 * radius = 2 * 3 = 7cm) of the cylinder being the two sides of the triangle formed.
Please check attachment for a diagram of the cut-out right angled triangle
To find the value of c, we employ the use of pythagoras’ theorem. This states that in a right angled triangle [( where one of the three angles in the triangle = 90), the square of the hypotenuse equals the sum of the squares of the other two sides , where the hypotenuse is the longest side and it faces the angle 90)]
Mathematically;
c^2 = 8^2 + 6^2
c^2 = 64 + 36
c^2 = 100
c = √100
c = 10cm
Answer:
%
Step-by-step explanation:
Answer:
X=4-2y/6
Y=4-6x/2
Step-by-step explanation:
For X:
1) -2y
Once you subtract 2y you are left with 6x=4-2y
2) Divide by 6 on both sides to get x alone
That would give you your answer of X=4-2y/6
For Y:
1) -6x
After subtracting 6x you would have 2y=4+6x
2) Like the steps above, you divide by 2 on both sides and that would give you your answer of Y=4-6x/2
Answer:
180
Step-by-step explanation:
10% of 300=30
30*6= 180 (to get 60 percent you multiply 10% by 6)
60%=180
