It is a semi circle
Being half of the circumference of a circle, a semi circle has one side
It is a semicircle.
find the circumferance as if it was a whole circle but when you get the answer divide it by 2
Its perimeter is half of its circumference plus its diameter
Well the circumference equation is 2pi r and a semi-circle is half of a full circle so the circumference is 15.71 inches.
It is a semi circle
Being half of the circumference of a circle, a semi circle has one side
-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).
It is a semicircle.
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
circumference or perimeter of the semi-circle = (diameter*pi)/2 + diameter
2r+pi r
find the circumferance as if it was a whole circle but when you get the answer divide it by 2
Its perimeter is half of its circumference plus its diameter
Measure the diameter of the circle,this is a line taken right across the circle that goes through the centre. Now multiply by pi =3.142 and divide by 2 to get the length of half the circumference.
add the perimeter of the rectangle, minus the side that'c covered by the semi circle. then, find the circumference of the semi circle [diameter x pi, divided by 2] and addd them together
