Answer:
<h3>The answer is 157.08 mm</h3>
Step-by-step explanation:
Circumference of a circle = πd
where
d is the diameter of the circle
From the question
d = 50 mm
The circumference of the circle is
C = 50π
= 157.07963267949…
We have the final answer as
<h3>157.08 mm</h3>
Hope this helps you
Answer:
You will need to use simultaneous equations.
Method:
Get both equations to have the same subject, in this case we will multiply the first equation by 4
1) 2x-y = -1
Becomes
1) 8x-4y = -4
Then make both equations equal to 4y.
1) 8x+4= 4y
2) 4y = -5x + 17
Because they both equal 4y, that means they are equal to each other.
8x+4 = -5x+17
Now solve for x.
13x = 13
x = 1
Now that we have x, we can substitute it back into either equation to get y. I will use equation 1 because it is less complex.
2x-y = -1
2(1)-y = -1
y = 3
