530.66 m²

Step-by-step explanation:

The equation to find a circle's area is $\pi$ $r^{2}$ . We just need to plug in the radius.

$\pi$ $13^{2}$

= 3.14*169

= 530.66

Answer:

Necklace cost $144 and bracelet cost $48

Step-by-step explanation:

call x is the price of necklace, y is the price of bracelet

because necklace cost 3 time as much as the bracelet

=> 3x = y

A necklace and a bracelet cost $192

=> x + y = 192

=>set of equations

3x = y and x+y = 192

x= 3y and 3y + y = 192

=> y = 48 and x = 3 . 48 = 144

Answer:

$1\frac{1}{6} = x$

Step-by-step explanation:

$\frac{x}{\frac{4}{3}} = \frac{7}{8} \\ \\ \frac{4}{3} \times \frac{7}{8} = \frac{28}{24} = 1\frac{4}{24} = 1\frac{1}{6}$

Use multiplication [inverse of division] to figure this out.

* $1\frac{1}{3} = \frac{4}{3}$

I am joyous to assist you anytime.
