Consider the straight side as the diameter of a circle, find the circumference of the circle, calculate half the circumference and then add it to the diameter.
circumference = pi x diameter = 3.14 x 36 = 113.04
perimeter of semicircle = 1/2 circumference + 36 = 56.52 + 36 = 92.52

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.
Has one straight side and one curved side?
A shape that has one straight side and one curved side is called a semicircle. A semicircle is a two-dimensional geometric shape that consists of half of a circle. The straight side is the diameter of the circle, while the curved side is the arc that forms half of the circle's circumference.

The distance around a closed plane figure?
The distance around a closed plane figure is called the perimeter. The perimeter of a figure can be calculated by adding together the lengths of each side.
How do you find the radius of a semi circle with an equal perimeter to a rectangle with 1 side 3cm and the other side equal to the radius?
Suppose the radius is R cm. Then the perimeter of the rectangle is 2*(3+R) = 6 + 2R cm. The length of the arc of the semicircle is pi*R and the length of the diameter is 2*R so the perimeter of the semicircle is pi*R + 2R The two perimeters are equal so 6 + 2r = pi*R + 2R That is, 6 = pi*R and so R = 6/pi
How do you measure the perimeter of a semicircular table?
use a ruler!!!!how do you use a ruler with a semicircle EDIT: Assuming you can measure the length of the straight side.. to find the perimeter - treat it as a whole circle, and find the circumference through multiplying the diameter (straight edge) by Pi. Then - divide that figure by 2, and add on the length of the straight side ! Snakester1962 (Supervisor)

How do find the circumference of a recttangle and semicircle put together?
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.

None because it has 1 straight side and no angles
How does Doubling the side lengths of a figure affect its perimeter?
The perimeter is doubled.
