A≈28.27cm² is the area of the circle with diameter 6cm
as
 <span>Area of a circle = pi * r² 

Since the diameter is twice the radius, the radius is 6cm/2 which is 3cm. 

pi * 3 * 3 

= 28.2743339cm²</span>

Area of circle = πd²/4,    where d = diameter
 
                      = π*6*6/4 = 9π ≈ 9 *3.1416 ≈ 28.2744 cm²

Area ≈ 28.27 cm²

Hope this explains it.

How many solutions does the equation have? |h| − 8 = 4<br> no solution, one solution, two solutions
Gennadij [26K]

Since the solution to the system of equation is 12 and -12, hence the equation has 2 solutions

<h3>Modulus functions</h3>

Modulus functions are functions that can either be positive or negative. Given the modulus function below;

|h| − 8 = 4

The modulus of h can both be negative and positive

If the modulus of h is positive then;

h - 8 = 4

Add 8 to both sides

h-8 + 8 = 4 + 8

h = 4 + 8

h = 12

If the value of h is negative

-h - 8 = 4

-h = 4 + 8

h =-12

Since the solution to the system of equation is 12 and -12, hence the equation has 2 solutions
