I am having trouble with this problem ​

12.566 sq inches

Step-by-step explanation:

12.57

Step-by-step explanation:

The formula to find the area of a circle is A=πr^2.  Radius is half the diameter, so the radius is 2.  2 squared is 4.  Now the equation is A=4π.  π, (pi,) should be used as 3.14 in this equation since your answer has to be a decimal.  3.14 multiplied by 4 = 12.57.    

answer: the triangle abc translated 2 units left and 5 units upward. te translation rule is t-2,5(x,y).

explanation:

it is given that randy draws triangle abc on the coordinate plane with vertices a(7, –4), b(10, 3), and c(6, 1). after translation the coordinates of the image are a′(5, 1), b′(8, 8), and c′(4, 6).

in the translation the position of a figure charges without making any in size and shape.

let the triangle shifts by the rule ta,b(x,y), where a is horizontal shift and b is vertical shift then,

since a(7,-4) and a'(5,1), therefore,

compare the coordinates.

a=-2

b=5

so the translation rule is t-2,5(x,y).
