Find the radius of a circle given that the circumference is 75.4 cm .

1 answer:

4 0

The circumference of a circle is given by:
$C = 2 \pi r$

We can solve for r:
$r = \frac{C}{2 \pi }$

Plug in given values:
$r = \frac{75.4}{2 \pi }$

Plug it into a calculator to get:
$r = 12$

So, your answer is: r = 12cm.

Makayla has $8 to buy tickets at the school fair. Each ticket costs @1.5. Which inequality best represents how many tickets she

cricket20 [7]

Answer:

$n\le 5$

Step-by-step explanation:

Let n be the number of tickets Makaya has to buy.

If the cost of one ticket is $1.5, then the cost of n tickets is $1.5n.

Makayla has $8 to buy tickets at the school fair, thus

$1.5n\le 8\\ \\n\le \dfrac{8}{1.5}\\ \\n\le \dfrac{80}{15}\\ \\n\le \dfrac{16}{3}\\ \\n\le 5\dfrac{2}{3}$

The maximum number of tickets Makaya can buy is 5, so

$n\le 5$
