Question

Find the area of thi emi-circle with diameter, d = 8cm. Give your anwer a an expreion in term of π

Answer 1

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.
