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.
Ah, what a lovely question! To find the perimeter of a semicircle, you'll need to add the curved part (half the circumference of a full circle) to the diameter of the semicircle. Since the diameter is 8cm, the radius is half of that, which is 4cm. The perimeter would then be half the circumference of a full circle (pi times the diameter) plus the diameter, giving you a total of 4π + 8 cm.
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.
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)
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

If you are given the diameter 'D' of the circle: the full circumference is (pi times D) the perimeter of the semicircle is half this plus the diameter Therefore: Pi x D /2 + D
Circumference of a circle = (pi) x (diameter)
diameter times 3.14159
You can multiply the radius by pi to get the length of the semicircle.
Divide the circumference by 2*pi because 2*pi*radius = circumference
2r+pi r
PI times the DIAMETER
