area of a circle with a diameter of 6

The area of the circle is 28.26

Step-by-step explanation:

Given that,

The diameter of the circle = 6

The formula to find the area of the circle is given by,

Area of the circle = πr²

where,

The steps to find the area of a circle is to square the radius or multiply it by itself. Then multiply the squared radius by 3.14 to get the area.

Now, to find the radius = diameter /2

Radius = 6/2

r = 3

Substitute r = 3 in the area formula,

Area of circle = (3.14) × (3)²

⇒ 3.14 × 9

⇒ 28.26

Therefore, the area of the circle is 28.26

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".
