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 area of a semicircle whose radius is 5 cm?
50.25cm
What is the perimeter of a 12 cm semicircle?
it is 6 and 2 or 3 and 3
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.
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
