What is the perimeter of a 12 cm semicircle?
it is 6 and 2 or 3 and 3
What is the semi circle radius 10cm?
It is half of a circle; the circle's radius (and that of the semicircle) is 10 cm.
What is the radius of a circle of perimeter 20 cm?
Pi= 3.1416 circle / 3.1416=diameter
A semi circular sheet of diameter 28 centimetre us bent into an open conical cup find depth and capacity of a cup?
Depth of cone = Radius of semicircle = 28/2 cm = 14 cm Circumference of the base of cone = Arc of semicircle = 0.5*pi*28 = 14*pi cm Therefore radius of base = 14*pi/(2*pi) = 7 cm Capacity = 1/3*pi*r2*h where r is the radius of the base of the cone. = 1/3*pi*72*14 = 718 cm3
Perimeter of a square with 7-cm sides?
The perimeter is 7 cm
What is the perimeter of a 8cm semicircle?
8*pi + 16 = 41.13 cm (approx)It depends on whether 8 cm is the radius or diameter of the semicircle.
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
What is the perimeter of semi circle radius 7cm?
The perimeter of a semicircle consists of the curved part and the straight diameter. The curved part can be calculated using the formula for the circumference of a full circle, which is (C = 2\pi r). For a semicircle, it would be (\pi r), so for a radius of 7 cm, the curved length is ( \pi \times 7 \approx 21.99 ) cm. Adding the diameter (which is (2r = 14) cm), the total perimeter is approximately (21.99 + 14 = 35.99) cm.
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 semi circle with the straight edge measuring 10cm?
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.
What is the perimeter of a semicircle if the diameter is 8cm?
Well, darling, the perimeter of a semicircle is the sum of the semicircle's curved edge (half the circumference of a full circle) and the diameter. So, with a diameter of 8cm, the curved edge would be half of the circumference of a circle with a diameter of 8cm, which is 8π cm. Add that to the diameter, and you get a sassy perimeter of 8π + 8 cm, or approximately 33.13 cm.
What is the area of a semicircle whose radius is 5 cm?
50.25cm
What is the perimeter of a 12 cm semicircle?

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
What is the semi circle radius 10cm?
It is half of a circle; the circle's radius (and that of the semicircle) is 10 cm.
What is the radius of a circle of perimeter 40 cm?
Radius = 40/2pi cm
What is the approximate area of a semicircle whose radius is 2Cm?
2pi sq cm
