Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.
10 cm (diameter is double the radius)
10 cm; the diameter of a circle is twice its radius.
The radius will be half the diameter 10/2 = 5
radius 5 cm diameter 10 cm
5cm
The answer will depend on what measure of the semicircle is 5 inches: its radius or diameter.
10 ft
5.
Perimeter = (2*pi*5*1/2)+10+16+16 = 57.70796327 or 58 feet
5'
diameter = radius x 2 radius = 5ft / 2 = 2.5 ft you may try using the calculator linked below
Radius of circle: 10/2 = 5 feet
50.25cm
The straight edge of the semicircle is the diameter, which measures 10 cm. The radius is half of the diameter, so it is 5 cm. The perimeter of the semicircle includes the curved part plus the diameter: the curved length is (\pi \times r), which is (\pi \times 5 = 5\pi) cm. Therefore, the total perimeter is (5\pi + 10) cm, approximately (10 + 15.71 = 25.71) cm.
Diameter of a circle is always twice the radius. So if the radius is 2.5 then diameter is 2x 2.5=5
The diameter is twice the radius so a circle with a radius of 2.5 will have a diameter of 5.
The radius of a circle is half of its diameter. Therefore, for a circle with a diameter of 5 units, the radius would be 5 divided by 2, which equals 2.5 units.
