Answer:
The area of semicircle is <u>8π cm</u><u>²</u>.
Step-by-step explanation:
<u>Given</u> :
Here we have given that the diameter of a semicircle is 8 cm. So, the radius will be 8/2 = 4 cm.
<u>Calculating</u> :
Now, finding the area of semicircle by substituting the values in the formula :











Hence, the area of semicircle is 8π cm².

Answer:
A = 8π cm²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius )
Here diameter = 8 , then r = 8 ÷ 2 = 4
The area of half a circle is then
A =
π × 4² =
× π × 16 = 8π cm²
