How do I find the arc length with given radius &amp; central angel?
ella [17]

The length of an arc subtended by a central angle is proportional to the circle's circumference. If the given central angle has measure \theta and the circle has radius r, then the arc has length \ell such that

\dfrac{\ell}\theta=\dfrac{2\pi r}{2\pi}=r

where \theta is given in radians. Then

\ell=r\theta

If \theta is given in degrees, then

\dfrac{\ell}\theta=\dfrac{2\pi r}{360}\implies\ell=\dfrac{\theta\pi r}{180}

If 2a - b = 4 , find a.
julia-pushkina [17]
<h2>Answer:  a = ¹/₂ (4 + b)</h2>

<h3>Step-by-step explanation:</h3>

To solve for 'a' we have to make it the subject of the equation. Since there are two unknowns ('a' & 'b'), we won't get a numerical value of 'a', but an expression in terms of the second unknown 'b'.

Since 2a - b = 4                    <em> [add 'b' to both sides]</em>

then          2a = 4 + b             <em>[divide both sides by 2 = multiplying by  ¹/₂]</em>

                   a = ¹/₂ (4 + b)

Evaluate the expression 6+[(-24)÷6]/19
zlopas [31]
The order of operations is defined by the acronym PEMDAS (Parentheses, Exponents, Multiplication, Division, Addition, Subtraction).
Therefore
6 + [(-24) ÷ 6] / 19
= 6 + [ -24/6 ] / 19      handle parentheses first
= 6 + (-4) /19
= 6 - 4/19                   handle division
= 110/19
= 5 5/9

Answer:  
\frac{110}{19} \,\, or \,\, 5 \, \frac{5}{19} \,\, or \,\,  5.79
