A circle with center at (12,−1) passes through (0,−1). Find the circumference and area of the circle in terms of p.

madreJ [45]

Answer:

C = 75.36

A = 452.16

Step-by-step explanation:

Find the radius r by finding the distance between (12,-1) and (0,-1) using the distance formula.

$d = \sqrt{(12-0)^2 + (-1--1)^2} =\sqrt{(12)^2 + (0^2} =\sqrt{144+0} =\sqrt{144}=12$

The radius is 12.

So the circumference of the circle is $C = 2\pi r = 2\pi 12 = 24\pi = 75.36$

So the area of the circle is $A = \pi r^2\\A = \pi 12^2\\A = 144\pi\\A = 452.16$

What is 3 1/8 - 1/2

irina1246 [14]

Answer:

$\frac{21}{8}$

Step-by-step explanation:

Given: $3\frac{1}{8} - \frac{1}{2}$

Let's changed that mixed number to an improper fraction. Now we get:

$\frac{25}{8} - \frac{1}{2}$

Let's find out least common denominator. This one is easy, the LCD is 8. Now that we know the LCD, let's convert both our fractions:

$\frac{25}{8} - \frac{4}{8}$

We can use $\frac{4}{8}$ because it is equal to $\frac{1}{2}$ . Now, all we need to do is subtract the numerators:

$\frac{25}{8} - \frac{4}{8}=\frac{21}{8}$
