A 57-inch television screen has an aspect ratio of 4:3. Find the scale factor (x), find the length and width, and calculate the

natulia [17]

tv-sets are rated by the screen size and the screen size comes from the length of its diagonal.

so a 57" TV has a 57" diagonal.

Check the picture below.

$\bf \stackrel{length}{4\left( \cfrac{57}{5} \right)}\implies \cfrac{228}{5}\implies 45\frac{3}{5}~\hfill \stackrel{width}{3\left( \cfrac{57}{5} \right)}\implies \cfrac{171}{5}\implies 34\frac{1}{5} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ \stackrel{Area}{\cfrac{228}{5}\cdot \cfrac{171}{5}}\implies \cfrac{38988}{25}\implies 1559\frac{13}{25}$

Circle O has a circumference of approximately 28.3 cm. What is the approximate length of the radius, r?

Scrat [10]

Answer:

4.5 cm.

Step-by-step explanation:

We have been given that circle O has a circumference of approximately 28.3 cm.

We will use circumference formula to solve for the radius of our given circle.

$\text{Circumference of a circle}=2\pi r$

Upon substituting the measure of circumference in above formula we will get,

$28.3=2\pi r$

$r=\frac{28.3}{2\pi}$

$r=4.504084889500638\approx 4.5$

Therefore, the radius of circle O is 4.5 cm.
