velikii [3]

Answer:

$\dfrac{2}{3}$

Step-by-step explanation:

Given the quotient: $4\dfrac{2}{3} \div 7$

Step 1: Write $4\dfrac{2}{3}$ in improper fraction.

$4\dfrac{2}{3}=\dfrac{14}{3}$

Therefore:

$4\dfrac{2}{3} \div 7=\dfrac{14}{3} \div 7$

<u>Step 2:</u> Change the division sign to multiplication by taking the reciprocal of 7

$\dfrac{14}{3} \div 7 =\dfrac{14}{3} X\dfrac{1}{7} \\$Simplify\\\\=\dfrac{2}{3}$

Find the area of the circle. Round your answer to two decimal places, if necessary.

Arlecino [84]

Answer:

Step-by-step explanation:

The equation for the area of a circle is A= $\pi$ $r^{2}$ .

A=area

r=radius

We were given the diameter of the circle not the radius, so we need to solve for the radius.

Radius=(1/2)Diameter So,

(1/2)6=3mm

Now we can solve for the area.

3^2(3.1415926)=28.2743mm

Now round to two decimal places.

28.27mm
