Find the radius of the circle whose equation is x^2 + y^2 = 4.

KATRIN_1 [288]

Answer:

Radius of the given circle is r = 2.

Step-by-step explanation:

Given equation of the circle is $x^2 + y^2 = 4$ .

Now we need to find the radius of the given circle $x^2 + y^2 = 4$ .

To find that let's compare with the formula of the circle with is $x^2 + y^2 = r^2$ , where r is the radius.

We get $r^2 = 4$

take square root of both sides.

$r=2$

Hence radius of the given circle is r = 2.

The three sides of a triangle are n, 3n + 5, and 4n − 9. If the perimeter of the triangle is 68 feet, what is the length of each

MissTica

4n - 9 + 3n + 5 + n = 68

combine like terms

8n - 4 = 68

addition property of equations

8n = 72

division property of equality

n = 9

SIDES:

n = 9

3n + 5 = 32

[ 3(9) + 5 = 32 ]

4n - 9 = 27

[ 4(9) - 9 = 27 ]
