What is the area of each semicircle to the nearest square meter?
Needs more information!
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
What is area of semicircle?
The area of a semicircle is half of the area of a circle. The area of a circle is pi x radius x radius. So the area of a semicircle is 1/2 x pi x radius x radius or (pi x radius x radius) / 2.
What is the area of a semicircle when the radius is 21?
The equation for area of a circle is A=pi x R x R. A semicircle is half a circle, so we calculate the area of a circle and divide by 2. The area of the circle would be approximately 1384.74. Thus the area of the semicircle would be 692.37.
