What is the area of each semicircle to the nearest square meter?
Needs more information!
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.
How do you find the radius of a semicircle?
it is have the diameter
How do you find the area of a rectangle inside of the enclose semicircle if the diameter is 28cm?
It can have any value up to 392 square cm.
What is the formula to find the area of a semicircle?
A/2 = ( pi r^2) / 2 Where 'A; is the circle area. So A/2 is the semicircluar area.
How do you find the area of a semi-circle if you know the diameter?
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
What is the area of a 12 inch semicircle?
Area in square inches = (pi*radius^2)/2
What is the area of each semicircle to the nearest square meter?
Needs more information!
Calculate the area of semicircle with radius 4 meters?
An area of a circle is pi*r2 - so an area of a semicircle is 0.5*pi*r2: 0.5*3.14*42 = 25.13 square meters
What is the equation to solve the area of a semicircle?
Area of a semicircle = (pi*radius^2)/2
How do you find the area of a rectangle with a semi circle attached to it?
Calculate the area of a rectangle and of the semicircle separately, then add.
How do you find the area of a semi-circle radius 10cm?
πr² is the formula for finding the area of a circle. To find the area of a semicircle just divide the answer by two. So take the radius, square it, which in this case would be 100, multiply it by π [pi (3.14)] and divide it by two.
What is the area of the semicircle if the length of the arc of a semicircle is 10 and pi feet?
It is 27.49 units.
If the diameter of a pizza was 50cm and it was a perfect semicircle what is the area of the smallest square box in square centimetres that could contain the half pizza?
i need the answer asap plz
How do you find the area of circle when its half of the circle?
Find the area of the whole circle and divide by two. Area of semicircle = 0.5*pi*r2, where pi = 3.14159 and r is the radius
