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
If the radius of a circle is 4 cm what is the diameter?
Diameter: 2*4 = 8 cm
What is the diameter of a circle 8 cm rounded to the nearest tenth?
8.0
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?
trapezoid = 1/2 sum of bases x height = 104 semicircle = 1/2 pi x diameter squared/4 = 100.48 total = 204.48 sq ft
What is the circumference of a circle with diameter of 8 cm?
Its circumference is: 8*pi cm
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 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.
How do you find the area of a circle that measures the diameter of 8 cm?
The formula for the area of a circle is: A = pi r2 where r is the measure of the radius. If the diameter of a circle is 8 cm, then the radius is half of that measure or 4 cm. Plug that into the formula and use 3.14 to approximate pi. A = 3.14(4)2 A = 3.14(16) Area is approximately 50.24 square cm.
What is the radius of a circle with a diameter of 8 centimeters?
Radius = Diameter / 2 In this case, diameter = 8 cm so radius = 4 cm
