Find the perimeter of a semi circle with a radius of 47cm

To find the circumference of a circle the equation is 2*pi*r
pi=3.14 
and the radius which is given is 47 
So 3.14*2=6.28
6.28*47= 295.16 then divide that bu two because it's a semi circle is 147.58 cm.
Therefore the perimeter of a semicircle is 147.58 cm

Step-by-step explanation:

Area of rectangle = 4w - 10

Take 2 as common factor

Area of rectangle = 2(2w - 5)

Thus the given expression is factored

Area of rectangle = l x w

area of rectangle = 2(2w - 5)

When we multiply 2 with 2w - 5 we get the area of rectangle

From above we can say,

Length = 2 or 2w - 5

Width = 2w - 5 or 2
