Half the Circumference + the DiameterCircumference of a circle = pi X d ,so perimeter of a semi-circle = (3.142 X Diameter) + Diameter

It is: (pi*radius)+(diameter)

Circumference of a circle = (pi) x (diameter)

4*pi*r2. because surface area is equal to circumference of circle.

If the semicircle is placed on 1 side of the rectangle:Find the total perimeter(circumference) of the side opposite to the one with the semicircle's base and the 2 sides perpendicular to the semicircle's base.The formula for circumference of a circle is 2πr.Thus for the semicircle we will take the circumference as πr.Find the sum of 1st and 2nd points. This is the final answer.

There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter

The circumference of a semicircle is pi times the radius plus the diameter.

diameter times 3.14159

circumference = pi multiplied by the diameter

Circumference of a circle = (pi) x (diameter)

Divide the circumference by 2*pi because 2*pi*radius = circumference

You can multiply the radius by pi to get the length of the semicircle.

3.14 to the 2 power
