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!

Solve the logarithmic equation for x.

aev [14]

Answer:

x = 2 or x = 4

Step-by-step explanation:

Solve: 2 log x = log 2 + log(3x - 4)

log (x^2) = log 2 + log (3x - 4)

log (x^2) = log [2*(3x - 4)]

x^2 = 2*(3x - 4)

x^2 = 6x - 8

x^2 - 6x + 8 = 0

factor:

(x - 2 )(x - 4) = 0

x = 2 or x = 4

Does the point (6,3) satisfy the equation y = 4(x – 5)?

Darina [25.2K]

Answer:

Step-by-step explanation:

plug (6,3) into the given equation to find out

3 = 4(6-5)

3 = 4(1)

3 = 4

since 3 does not equal 4, the point (6,3) does not satisfy the equation y=4(x-5)
