If the diameter of a circle is above 9mm. What would the area of the circle be?

Best Answer Gets

A = 63.585 mm or round if needed

Step-by-step explanation:

Formula is A = pi radius squared

9 mm ÷ 2 mm = 4.5 mm

3.14 x 4.5 x 4.5= 63.585 mm

Hope this helped have a great day :)

It might be at least 63.585 I don't have all the info

y=mx+b

step-by-step explanation:

m is slope, b is y-intercept

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
