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.


What is the perimeter of a 8cm semicircle?

8*pi + 16 = 41.13 cm (approx)It depends on whether 8 cm is the radius or diameter of the semicircle.

You have to understand that two radius makes up a diameter. That means if given the radius you can just times it by 2 to get the diameter 4 cm= 8cm diameter


What is the radius of a circle with a diameter of 8cm?

Since diameter is 2 x pi x radius, 8 cm / 2 / 3.14 is about 1.3cm. Specifically, 1.2732cm.


If the radius of a circle is 4 cm then what is the diameter?

The diameter would be 8cm, because the diameter is always double the radius. That's why the formula 2'Pi'r is also known as 'Pi'd.
