It is: pi*4^2 divided by 2 = 8/pi which is about 25 square cm

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.

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.

it is have the diameter

It can have any value up to 392 square cm.

A/2 = ( pi r^2) / 2 Where 'A; is the circle area. So A/2 is the semicircluar area.

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.

Area in square inches = (pi*radius^2)/2

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

Area of a semicircle = (pi*radius^2)/2

Calculate the area of a rectangle and of the semicircle separately, then add.

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.

It is 27.49 units.

i need the answer asap plz

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
