Use the fact that the length of an arc intercepted by an angle is proportional to the radius to find the arc length given that r

Komok [63]

Answer:

The required length is 37.68 cm

Step-by-step explanation:

We have given the radius of which is 3 cm and $\theta$ which is $\pi\cdot 4$

We will use $\pi=3.14$

We know the formula for length of arc which is:

length of arc=radius x angle

We will substitute the values given we will get:

$length=3(3.14)(4)$

$length=37.68$

Hence, the required length is 37.68 cm

Which line is parallel to the line ‘y = 1/2x + 5’ and passes through the

Softa [21]

Answer:

B. y=1/2+2

Step-by-step explanation:

since parallel lines always have the same slope, the only two possible answers could be B and C. in order to find if one of those goes through point (-2,1), we have to set up an equation to find the base:

1=1/2(-2)+b

1=-1+b

2=b

We can plug in the base with the slope for the equation and the new equation would be y=1/2x+2
