Answer:

8.2

Step-by-step explanation:

We can use the distance formula: $\sqrt{((x_2 - x_1)^2 + (y_2-y_1)^2}$

$\sqrt{(10-2)^2 + (7-9)^2} = \sqrt{8^2 + (-2)^2} = \sqrt{64+4} = \sqrt{68} = 2\sqrt{17} = 8.2$

The face of a clock has a circumference of 63 in. What is the area of the face of the clock?

ryzh [129]

Answer:

The area of the clock $= 315.41\ inch^{2}$

Step-by-step explanation:

We have been given the face of the clock that is $63\ in$

So that is also the circumference of the clock.

Since the clock is circular in shape.

So $2\pi(r)=63\ inch$

From here we will calculate the value of radius $(r)$ of the clock that is circular in shape.

Then $2\pi(r)=63\ inch =\frac{63}{2\pi} = 10.02\ in$

Now to find the area of the clock we will put this value of (r) in the equation of area of the circle.

Now $\pi (r)^{2}=\pi(10.02)^{2}=315.41\ in^{2}$

So the area of the face of the clock = $315.41\ in^{2}$

the ratio of rock music to total CDs that Ella own is 25/40 polo has 50 rock music CDs the ratio of rock music to total CDs in h

cluponka [151]

If Polo has $n$ CDs, then $\frac{50}n=\frac{25}{40}$ hence $n=\frac{50\cdot40}{25}=80$

Hence, they have a total of $80+40=\boxed{120\text{ CDs}}$
