Sadly, the answer to your question is 'No'. The work written under
the problem on the paper is not correct ... because you tried to do
too much !
You can't combine 'm' terms with 'n' terms or with plain numbers.
They all need to stay separate all the way to the end.
So, actually, your first written line is the answer . . . <em>7m - 35 + 3n</em>
That's as far as you can go. You can't combine these terms. Stop there !
Here is the complete question.
Answer:
3.7 meters
Step-by-step explanation:
From the given information:
The radius is 3m
The central angle XYZ = 70°
To calculate the circumference of the circle:
C = 2 π r
C = 2 × 3.142 × 3
C = 18.852 m
Let's recall that:
The circumference length define a central angle of 360°
The approximate length of minor arc XZ can be determined as follow:
Suppose the ≅ length of minor arc XZ = Y
By applying proportion;
Y(360) = 18.852 × 70
Y = 1319.64/360
Y = 3.66
Y ≅ 3.7 m
