What is the area of a semicircle if the diameter is 8 cm?
It is: pi*4^2 divided by 2 = 8/pi which is about 25 square cm
What is the perimeter of a semicircle if the diameter is 8cm?
Ah, what a lovely question! To find the perimeter of a semicircle, you'll need to add the curved part (half the circumference of a full circle) to the diameter of the semicircle. Since the diameter is 8cm, the radius is half of that, which is 4cm. The perimeter would then be half the circumference of a full circle (pi times the diameter) plus the diameter, giving you a total of 4π + 8 cm.
What is the diameter of a circle 8 cm rounded to the nearest tenth?
8.0
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?
Oh, what a lovely combination of shapes you have there! Let's start by finding the area of the semicircle, which is half the area of a full circle. Then, we can calculate the area of the trapezoid using its height and the average of its bases. Finally, we add these two areas together to find the total area of your beautiful figure. Remember, there are no mistakes, just happy little accidents in math!
What is the area of a semicircle if the diameter is 8 cm?
It is: pi*4^2 divided by 2 = 8/pi which is about 25 square cm
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?
Area = 50.265 cm2Circumference = 25.132 cm
If a circle has diameter of 8 Cm what is the area?
64 pi
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.
