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

Answer:
había 18 DVDs al principio
Step-by-step explanation:
si procedemos desde el final del problema , sabemos que :
total que le quedaba después de darle los CDs a Juan - lo que fue para la hermana = lo que le sobró
x - x/3 = 6
2/3*x = 6
x= 6 * 3/2 = 9
por lo tanto tenia x=9 DVDs después de entregarle a Juan los suyos
también sabemos que
DVDs que tenia al principio - lo que fue para Juan = 9 DVDs
y - y/2 = 9
y/2 = 9
y= 18
finalmente había y= 18 DVDs al principio
