perimeter of a semi circle= Diameter x Pi (3.14... etc.)
then divide it by 2.
then add the value of the diameter to the answer.
there may be a quicker way but i just figured this way out using the how to find the circumference of a circle...and yea.
i hope this helps :/ ahaha

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 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
What is the formula for the perimeter of a semicircle?
If you are given the diameter 'D' of the circle: the full circumference is (pi times D) the perimeter of the semicircle is half this plus the diameter Therefore: Pi x D /2 + D
The radius of the semicircle is 5 feet and the dimensions of the rectangle are 10 ft by 16 ft The semicircle is attached to the width of it What is the perimeter?
Perimeter = (2*pi*5*1/2)+10+16+16 = 57.70796327 or 58 feet
If a diameter of the semicircle is 14cmfind its perimeter?
Perimeter = Circumference/2+Diameter Perimeter = (pi*14)/2+14 = 35.99114858cm or 36cm correct to two significant figures.
If the base of a semicircle is a feet What is its perimeter?
The circumference of a circle = 2π r = π a (where a is the base of the semicircle and is also the diameter of the circle) The perimeter of the semicircle = half the perimeter of the circle + the base length The perimeter of the semicircle = πa/2 + a = a(1 + π /2) feet
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 formula of a semicircle in perimeter?
The perimeter of a semicircle with radius R is pi*R + 2*R = R*(pi + 2)
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
Perimeter of a semicircle when the Diameter is 8?
Perimeter of a semicircle is the length of the half-circle plus the diameter. The whole circle would have a length of diameter times pi, but since it's only half... Perimeter of semicircle = (1/2*pi*D) + D
What is the perimeter of a semicircle that is 5 inches?
The answer will depend on what measure of the semicircle is 5 inches: its radius or diameter.
How do you calculate the radius of s semicircle?
Calculating the radius of a semicircle depends on what information about the semicircle is given.
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
How do we find a perimeter of a semicircle?
It is its diameter plus half of its circumference
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
What is the perimeter of a semicircle if it's radius is 280 cm?
Perimeter = (pi*280)+560 = 1439.645943 cm
