The <em><u>correct answer</u></em> is:

He can buy 3 packs of 10 or 30 single pieces.

Explanation:

He needs 30 pieces. Since they are sold in 10 packs, it would take 30/10 = 3 packs of 10.

Other than this, the pieces are sold as singles. This means he could also buy 30 single pieces.

Find the area of a sector with a central angle of 120° and a diameter of 7.3 cm. Round to the nearest tenth.

Andru [333]

Answer: $14cm^{2}$

Step-by-step explanation:

diameter=7.3cm

radius= $\frac{diameter}{2}$

= $\frac{7.3}{2}$

=3.65cm

angle =120°

area= $\frac{angle (tita)}{360}$ × $\frac{\pi r^{2} }{1}$

= $\frac{120}{360}$ × $\frac{22}{7}$ × $3.65^{2}$

= $13.95cm^{2}$

≅ $14cm^{2}$
