Answer:

Length of arc AB = 4π

Step-by-step explanation:

Formula to get the arc length is given by,

Length of arc = $\frac{\theta}{360}(2\pi r)$

Here, θ = central angle subtended by the arc AB

r = Radius of the circle

By substituting the values in the formula,

Therefore, length of arc AB = $\frac{120}{360}(2\pi )(6)$

= 40π

The distributive property states that:

a(b+c)=ab+bc.

or more generally: a(b+c+d)=ab+av+ad.

This is a very useful tool to perform multiplication.

For example, if we want to multiply 7 by 234, we can proceed as follows:

7*234=7(200+30+4)=7*200+7*30+7*4=1400+210+28=1610+28=1638

back to our problem,

4 * 24 = 4(20+4)=4*20+4*4=80+16=96 ($)

So, instead of multiplying 4 by 24, we multiplied 4 by 20 and 4, which is easier, and then added these together.

Answer:

4 * 24 = 4(20+4) [=4*20+4*4=80+16=96 ($)]
