Perimeter = (pi*7)+14 = 35.99114858 or about 36 units of measurement

Answer 2 (ylon2): Perimeter= 2*r+2*pi*r/2=r*(2+pi) = r*5.14=35.98 or about 36 units of measurement (ylon2 calkulated)

If diameter is 7 find perimeter of semi circle?

Pi times the diameter gives you the circumference. Then divide that answer by two. Then add in the diameter - and, voila, you have your answer as to the perimeter of a semicircle.


What is the perimeter of a circle if the radius is 7 m?

perimeter or circumference = 2*pi*7 m


How do you find the area of a semi circle or quarter circle when pi is twenty two sevenths and please include an example for both semi circle AND quarter circle?

The area of a circle is pi*r2, where r is the radius. In this case, 22/7 will be used for pi. Area of a semicircle: A semicircle is half of a circle, so the area will be half of a circle: A = (1/2)*pi*r2 Example: Find the area of a semicircle with a radius of 10 meters. A = (1/2)*(22/7)*(10)2 = (1/2)*(22/7)*(100) = 1100/7 or about 157.14 square meters Area of a quarter circle: A quarter circle is a forth of a circle, so the area will be A = (1/4)*(pi)*r2 Example: Find the area of a quarter circle with a diameter of 4 inches: (Notice that the diameter is given, so the radius in this case is 2 inches:) A = (1/2)*(22/7)*(22) = (1/2)*(22/7)*4 = 44/7 or about 6.286 square inches.

To find the perimeter of a rectangle simply add the length and width then double your answer.


How do you find the perimeter of a rectangle that is 12 inches long and 7 inches wide?

Perimeter = 12+12+7+7 = 38 inches


How do you find the perimeter of two concentric circles?

The perimeter of a circle is the same as it's circumference. To find this, you will need to know it's radius or diameter.For example, if the diameter of a circle is 7, you could do: pi times the diameter (which is 7), or, if you want to, you could half it and have; 2 times pi times 3.5. It doesn't matter which way you have it, you will still get the same answer if it is halved correctly.

A semi circular sheet of diameter 28 centimetre us bent into an open conical cup find depth and capacity of a cup?

Depth of cone = Radius of semicircle = 28/2 cm = 14 cm Circumference of the base of cone = Arc of semicircle = 0.5*pi*28 = 14*pi cm Therefore radius of base = 14*pi/(2*pi) = 7 cm Capacity = 1/3*pi*r2*h where r is the radius of the base of the cone. = 1/3*pi*72*14 = 718 cm3
