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.
How do you find the diameter of a semicircle when radius is given?
The diameter of the semicircle will be twice the radius.
How do you find the perimeter of a semicircle if its diameter is 45 cm?
Perimeter of the semicircle including its base: 180/360*pi*45+45 = 115.686 cm rounded to 3 decimal places
How do you find the perimeter of the circle of radius r?
by using formula 2. pie. r
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 do you find the perimeter of a semicircle?
The circumference of a semicircle is pi times the radius plus the diameter.
How do you find the diameter of a semicircle when radius is given?
The diameter of the semicircle will be twice the radius.
How do you find the radius of a semicircle?
it is have the diameter
How do we find a perimeter of a semicircle?
It is its diameter plus half of its circumference
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 find the perimeter of a semicircle if its diameter is 45 cm?
Perimeter of the semicircle including its base: 180/360*pi*45+45 = 115.686 cm rounded to 3 decimal places
How do you find the perimeter of the circle of radius r?
by using formula 2. pie. r
How do you find the perimeter of a semicircle with radius 7?
Perimeter = (pi*7)+14 = 35.99114858 or about 36 units of measurement Answer 2 (ylon2): Perimeter= 2*r+2*pi*r/2=r*(2+pi) = r*5.14=35.98 or about 36 units of measurement (ylon2 calkulated)
What is the perimeter of a semicircle if the diameter is 8cm?
Ah, what a lovely question! To find the perimeter of a semicircle, you'll need to add the curved part (half the circumference of a full circle) to the diameter of the semicircle. Since the diameter is 8cm, the radius is half of that, which is 4cm. The perimeter would then be half the circumference of a full circle (pi times the diameter) plus the diameter, giving you a total of 4π + 8 cm.
Find the perimeter of a semicircle of diameter 10cm?
First find the circumference of the whole circle using Pi x diameter. Halve the answer and add the diameter. Thus: 3.1416 × 10 = 31.416 ÷ 2 + 10 = 25.708cm So the perimeter of the semi-circle is 25.7cm
What is the formula to find the area of a semicircle?
Pi*radius squared is how to find the area of a semicircle
