Because it’s a square garden each side is the same meaning 84/4 will give you the length of each side, in this case 21. to work out the area it is length x width so 21 x 21 is 441!
The area of semi-circle is 8π cm² with diameter of 8cm.
What is area of semi-circle?
- The area that the semicircle occupies is that which is contained inside its perimeter. Half of a circle is a semicircle.
- The area of a semicircle will therefore be equal to half that of a circle. Both the radius and the diameter can be used to get the semicircle's area.
- The formula used to determine a semicircle's area in terms of radius "r" is written as follows:
Area of circle = πr²/2
- Area of semi-circle= πd²/8 is the formula used to determine a semicircle's area in terms of its diameter.
- The value of the constant is 22/7, or 3.14.
Given:
Diameter = 8cm
Area of semicircle = πd² / 8
=π8² / 8
= 8π cm²
Hence, the area of semi-circle is 8π cm².
