t2 ÷ (2( π + 4)
π = pi
Pi times the diameter gives you the circumference. Then divide that answer by two. Then add in the diameter - and, voila, you have your answer as to the perimeter of a semicircle.
Circumference or perimeter = 2*pi*radius or pi*diameter
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.
-- 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).
A rectangle does not have a diameter, as such, but the diagonal is similar enough. If the sides of a rectangle are x cm and y cm then, using Pythagoras's theorem, the diagonal is sqrt(x2 + y2) cm.
The circumference of the circle is larger than the perimeter of the rectangle.
Do you mean perimeter? If so....2 x length + 2 x width.
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
Area of circle = pi*212 = 1385.44236 square cm Area of rectangle = 1385.44236 square cm Lenght of rectangle = 1385.44236/18 = 76.96902 cm Perimeter of rectangle = 2(76.96902)+2(18) = 189.93804 cm
You need two measurements for a rectangle: length x width. If both are equal, you should say so (in this case, it is a square).
The perimeter or circumference of a circle = diameter times pi
The question cannot be answered. First, there is no information as to which measure of the rectangle is 14 units: a diameter, the perimeter, the area. Second, the answer to the question above does not provide sufficient information to answer the question.
The perimeter is the diameter times pi. So the perimeter is 20pi ft
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).
Perimeter = pi*diameter = 113.1 cm
A rectangle is an elongated square. It doesn't have a diameter; only circles have diameters.
You get 2 circles of diameter. If you were trying to find a perimeter, Never double the diameter. If you have a radius, You have to double it to get a perimeter.
