What is the perimeter of a semicircle if the diameter is 8cm?
To find the perimeter of a semicircle, you need to add the curved edge (half the circumference of a full circle) to the diameter of the semicircle. The formula for the circumference of a full circle is C = πd, where d is the diameter. Therefore, the circumference of the full circle is π(8) = 8π cm. The perimeter of the semicircle would be half of the circumference of the full circle plus the diameter, so it would be 4π + 8 cm, or approximately 20.28 cm.

If the radius of a circle is 4 cm what is the diameter?
Diameter: 2*4 = 8 cm
What is the area of a figure formed using a semicircle with a diameter of 16 feet and a trapezoid with a height of 8 feet and bases of 12 feet and 14 feet?
To find the area of the figure, we first need to find the area of the semicircle and the trapezoid separately, then add them together. The area of a semicircle is half the area of a full circle, which is πr^2, where r is the radius. In this case, the radius is half the diameter, so 16/2 = 8 feet. Therefore, the area of the semicircle is 1/2 * π * 8^2 = 32π square feet. The area of a trapezoid is calculated using the formula A = (1/2) * (b1 + b2) * h, where b1 and b2 are the lengths of the bases and h is the height. Plugging in the values, the area of the trapezoid is (1/2) * (12 + 14) * 8 = 104 square feet. Adding the areas of the semicircle and trapezoid together gives a total area of 32π + 104 square feet.

How much bigger is the area of a quadrant of radius 8 cm than a semicircle of a diameter 4 cm?
Twice as big.
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 area of a semicircle of a diameter Cm?
The area of a semicircle can be calculated using the formula ( A = \frac{1}{2} \pi r^2 ), where ( r ) is the radius. Since the diameter is given as ( Cm ), the radius ( r ) is ( \frac{Cm}{2} ). Plugging this into the formula gives ( A = \frac{1}{2} \pi \left(\frac{Cm}{2}\right)^2 = \frac{\pi (Cm)^2}{8} ). Thus, the area of the semicircle is ( \frac{\pi (Cm)^2}{8} ).

What is the area outside the triangle if the triangle is inscribed in a semicircle while the side length of triangle is 2underroot2?
Diameter of semicircle = 1 Area of semicircle = Pi/8 Area of triangle = 0.25 Area outside triangle = (Pi/8) - 0.25 = 0.1427 (rounded to 4th decimal).
What is the area and circumference of a circle with a diameter of 8 cm?

Perimeter of a semicircle when the Diameter is 8?
Perimeter of a semicircle is the length of the half-circle plus the diameter. The whole circle would have a length of diameter times pi, but since it's only half... Perimeter of semicircle = (1/2*pi*D) + D
Can you find the area of a circle if the diameter is 8 cm?
Yes, you can.
What is the diameter of a circle whose radius is 8 cm?
Diameter = Radius * 2 In this case, radius = 8 cm so diameter = 16 cm
What is the diameter of a circle if the radius is 8 Cm?
The radius is always exactly half of the diameter, so if the radius is 8 cm, then the diameter is 16 cm.
