The circumference of a circle is 62.8 centimeters. What is the circle's radius?
Kobotan [32]

Hello!

To solve this exercise, we must use the formula below:

\mathrm{C=2\cdot\pi\cdot r}

  • C = 62.8cm
  • π = 3.14
  • r = ?

Knowing these values, let's replace them in the formula to obtain r:

\mathrm{62.8=2\cdot\ 3.14\cdot r}\\\mathrm{62.8=6.28r}\\\mathrm{6.28r=62.8}\\\\\mathrm{r=\dfrac{62.8}{6.28}}\\\\\boxed{\mathrm{r=10}}

So, the radius of this circle is 10cm.

Hope this helps!

What is y and x in simple radical form
vodka [1.7K]

Answer:

Step-by-step explanation:

This is a 30°-60°-90° triangle, so the sides are in the ratio 1:√3:2

The side opposite the 90° angle is 16, so the side opposite the 30° angle is 8, and the side opposite the 60° angle is 8√3.

x = 8√3

y = 8

A city has a population of 230,000 people. Suppose that each year the population grows by 9%. What will the population be after
zloy xaker [14]

<u>Answer:</u>

<h2><u>385,733</u></h2>

Step-by-step explanation:

If it grows by 9% each year, you can simply do the current population times 109%. Because its an additional 9%.

230,000*109% = 250,700

After the first year, there is a population of 250,700 people.

250,700*109% = 273,263

After the second year, there is a population of 273,263 people.

273,263*109% = 297,856.67

After the third year, there is a population of 297,856.67 people.

297,856.67*109% = 324,663.77

After the fourth year, there is a population of 324,663.77 people.

324,663.77*109% = 353,883.509

After the fifth year, there is a population of 353,883.509 people.

353,883.509*109% = 385,733.025

After the sixth year, there is a population of 385,733.025 people

Round it up to 385,733 people.
