the vertices of triangle ABC are A(2,3), B(-1,2), and C(3,1). If DEF~ABC and DE = 4AB, what is the length of EF?

10000

step-by-step explanation: divide by 2,

step-by-step explanation:

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi
