Answer:
254.5m^2
Step-by-step explanation:
Use the formula for the area of a circle given the radius:
A = πr^2
A = 3.14(9)^2
A = 254.47m^2
Round to the nearest tenth:
A = 254.5m^2
So D x= 5 is the right answer

The number of white sweatshirts is 28
Step-by-step explanation:
Let ordered black shirts be represented by b
Let ordered white shirts be represented by w
So total sweatshirts will be represented by the equation
b+w=50
The total cost of the ordered sweatshirts will be represented by
10b + 12 w= $556
For simultaneous equations as;
b+w=50
10b+12w=556
solving the equations using substitution method where b=50-w
10(50-w)+12w=556
500-10w+12w=556
-10w+12w=556-500
2w=56
w=56/2= 28
b=50-w=50-28=24
Number of white sweatshirts is 28
