Answer:
A'B' = 34 units
Step-by-step explanation:
Since the dilatation is centred at the origin , then multiply the coordinates by 2
A' = (2(0), 2(- 7) = (0, - 14 )
B' = (2(8), 2(8) = (16, 16)
Calculate the length using the distance formula
d =
with (x₁, y₁ ) = A'(0, - 14) and (x₂, y₂ ) = B'(16, 16)
d =
=
=
=
= 34
Answer:
28.26 square feet
Step-by-step explanation:
Area of a circle is:
'r' is the radius.
We are given the diameter of 6ft. Since the diameter is twice the radius, the radius is 3 ft.
6/2 = 3
Using 3.14 for pi:
The area of the circle should be 28.26 square feet.
