D. 9pi square inches
The formula for the area of a circle is <span>π x r^2
Since the diameter is 6, the radius (r) is 3
3^2 = 9
This times pi will give you the area of the plate

Answer:
$35
Step-by-step explanation:
To solve this problem you need to know how what and how is percentage work. 
Percentage(%) is a unit that equals to 1/100 or one hundredths. So, 7% will be equal to 7*1/100= 7/100. The commission is given based on the price of the boat. If the boat sold at $500 the commission will be: 
commission= percentage * boat price
commission= 7/100 * $500
commission= $35
 
        
             
        
        
        
For #1
you would do 
8 + 8 + 5 + 5 = 26
so they use 26 inches of ribbon
for #2 
since there is 8 sides and each side is 3 feet we multiply 
8 x 3 = 24 
so the perimeter of her collage room is 24 feet
for #3
its cut off...
