How many equal length sides does a semicircle have?
None A semicircle is the shape of a protractor (or half a pizza). It has one straight side and one longer curved edge.
What is the name of a half circle?
A half circle is commonly referred to as a "semicircle." It is defined as the shape formed when a circle is divided into two equal halves by a diameter. In geometry, a semicircle includes the curved edge and the straight line segment that forms the diameter.
What is a figure that has only one curved surface?
A semicircle
What is the name of a 2d circle cut in half called?
A 2D circle cut in half is called a semicircle. This shape consists of one straight edge (the diameter) and one curved edge (the arc of the circle). Semicircles are commonly used in various fields, including geometry and design.
How do you find the perimeter of a shape that has a semicircle?
To find the perimeter of the curved section of the semi-circle: Perimeter of semicircle = Pi x radius If you also need to the find the perimeter of the straight part of the semicircle (the diameter), it is simply double the radius.
What is the perimeter of a semicircle with radius 8cm?
A semicircle is half a circle. So the perimeter of a semicircle is half the circumference of the whole circle plus the diameter, which is twice the radius: perimeter = 1/2 x 2{pi}r + 2r perimeter ~= 3.14x8 + 2x8 ~= 41.13cm

Half of a circle?
A semicircle is half of a circle, formed by cutting a circle along its diameter line. It has the same curved edge as a circle but only covers half the area. The formula for the area of a semicircle is 1/2 times π times the radius squared.
What does a semicircle look like?
it is half of a circle. just type semi circles in to google you'll probably find it there.
What is the different between a semicircle and a hemisphere?
A semicircle is a two-dimensional shape that is half of a circle, with a flat edge as the diameter. A hemisphere, on the other hand, is a three-dimensional shape that is half of a sphere, with a curved surface. Essentially, a semicircle lies in a plane, while a hemisphere is a solid object.
Is the edge on a cone straight or curved?
Curved, the edge is the on the opposite side of the tip.
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 shape has one curved side and 2 straight sides?
The shape that has one curved side and two straight sides is a semicircle. A semicircle is a two-dimensional shape that is half of a circle, with one curved side and two straight sides that connect at the endpoints of the curved side. The curved side of a semicircle is a semicircular arc, while the two straight sides are diameters that intersect at the center of the circle from which the semicircle is derived.
