artcher [175]

Answer:

14(y + 2).

Step-by-step explanation:

32 +2/3(21y - 6)

Distributing the 2/3 over the parentheses:

= 32 + 2/3*21y  + 2/3 * -6

Find the circumference of this figure. Show your calculations.
solong [7]

Answer:

Circumference of circle= 37.68 units

Circumference of sector= 6.28 units

Step-by-step explanation:

The given figure is a circle with given radius OB= 6 units.

The circumference of a circle is the total length of its boundary.

For the complete circle its circumference can be calculated by;

           Circumference= 2\pi r

                                 =2*3.14*6\\=37.68 units

For the circumference of the Sector with 60° in the figure, the circumference can be calculate by:

                              =\frac{60}{360}* 2*\pi*6\\\\=\frac{1}{6}*12*3.14\\\\ =2*3.14\\\\=6.28 units

So, the circumference of the full circle is 37.68 units and the circumference of the sector is 6.28 units.
