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

one twelfth. 1/12

Two measurements are indication of area. The area would be 144 square inches.

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.

1ft=12 inch area of each paver =(12 inch)*(12 inch) =(1 ft)(1 ft) =1 sq.ft area of total to be covered=(8 ft)(16 ft) =128 sq.ft no of pavers = (128 )/(1)=128

A 12-inch circle has an area of about 113.1 square inches.

A 6 x 9 inch oval is a 3 inch x 3 inch square with a semicircle of 3 inch radius at each end. The total area is, therefore, 9 + 9*pi = 27.3 sq inches. Note that an oval is NOT an ellipse.

It is 27.49 units.

The area of a circle that has a 12-inch diameter is: 113.1 square inches.

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.
