What is the formula for finding the perimeter of a semicircle?

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

What is the formula for finding the distance around A semicircle?

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

What is the formula for finding circumferencE when only diameter is given?

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

What is the formula of finding the circumference of a sphere?

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

What is the perimeter of a semicircle if the diameter is 8cm?

To find the perimeter of a semicircle, you need to add the curved edge (half the circumference of a full circle) to the diameter of the semicircle. The formula for the circumference of a full circle is C = πd, where d is the diameter. Therefore, the circumference of the full circle is π(8) = 8π cm. The perimeter of the semicircle would be half of the circumference of the full circle plus the diameter, so it would be 4π + 8 cm, or approximately 20.28 cm.
