If the ratio between the radii of the two spheres is 3:7, what is the ratio of their volumes?

1 answer:

4 0

Given that the dilation factor or scale factor between the two spheres is equal to 3:7, the ratio between their volumes is calculated by cubing the numbers in the ratio. That is,
3³:7³
This operation will give us an answer of 27:343

If the area of a circle measures 9π cm2, what is the circumference of the circle in terms of π?

8_murik_8 [283]

Answer: option B

Step-by-step explanation:

The circumference of a circle can be calculated with this formula:

$C=2\pi r$

Where "C" is the circumference of the circle and "r" is the radius of the circle.

The area of a circle can be calculated with:

$A=\pi r^2$

Where "r" is the radius.

Knowing the area, you can solve for the radius:

$r^2=\frac{9\pi cm^2}{\pi }\\\\r=\sqrt{\frac{9\pi cm^2}{\pi } }\\\\r=3cm$

Substituting into $C=2\pi r$ , you get that the circumference of this circle is:

$C=2\pi (3cm)=6\pi\ cm$

In-s [12.5K]

Since there is a 70% chance of making $12,000 so have that:

.70 × 12000 = 8400

Also, we have a 10% chance of breaking even, so we also have that:

.10 × 0 = 0

Finally, we have a 20% chance of losing $7400 so we also have that:

.20 × 7400 = 1480

Thus, putting it all together we have:

.70(12000) + .10(0) + .20(7400) = 8400 + 0 + 1480 = 9880

Therefore, the expected value is:

$9880
