Determine the equation of the circle with center (0,6) containing the point (74,2)
Lubov Fominskaja [6]

The circle with center (0,6) containing the point (74,2) has an equation of x² + (y - 6)² = 74.1²

<h3>How to calculate the equation of a circle</h3>

The equation of a circle is:

(x - h)² + (y - k)² = r²

Where (h, k) is the center and r is the radius.

The circle with center (0,6) containing the point (74,2). Hence:

Radius=\sqrt{(2-6)^2+(74 -0)^2}=74.1\ unit

The equation is:

x² + (y - 6)² = 74.1²

If the length and breadth of a rectangle are 10cm and 20cm respectively,find the length of its diagonal
irina [24]

L = 10

B = 20

so to find the diagonal you have to use Pythagorean theorem that is a^2 + b^2 = c^2

10^2 + 20^2 = X^2

X = root of 10^2 + 20^2

X = root of 100 + 400

X = root of 500

X = appox 22.36

(100+4z)20 distributive property to simplify each expression
Leya [2.2K]
You should multiply each number inside of the parenthesis by the number outside of the parenthesis. So, multiply 20 by 100 and then 4z and 20. Afterwards, you no longer need the parenthesis around your equation. So, you will be left with 2000 + 80z.
