How do you figure the perimeter of a semicircle if the the straight side is 36?

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

The sum of the side lenghts of a closed plane figure?
perimeter
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.
The perimeter of an iquilateral figure can be found by multiplying the number of sides by the length of one side?
no
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
What is the perimeter of a circle and the diameter of a circle?
Circumference (perimeter) of a circle = pi x diameter Diameter of a circle is the straight line distance from one side to the other which passes through the centre of the circle.
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)
A welcome mat on the front porch is a semicircle. The straight side of the mat is 36 inches. What is the perimeter of the mat?
92.55 inches
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.
How many corners does a semicircle have?
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.
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.
How are side lengths of a figure and perimeter related?
perimeter is the sum of all sides.
The sum of the side lenghts of a closed plane figure?
perimeter
How do you find the perimeter of any figure?
Find the distance of each side and add to find the total perimeter.
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.
When finding the perimeter of a figure on a grid why do you not count the spaces inside the grid?
That's because "perimeter" means the distance around something - not the spaces inside. If you count squares inside a figure, you are finding the AREA, not the PERIMETER.
What is the perimeter formula for a triangular prism?
There is no way to find perimeter from a 3D figure. However, you can find the perimeter of a side of a triangular prism by using perimeter formulas for a parallelogram or triangle.
