Answer:
Perimeter = 42 units Area = 57.73 square units
Step-by-step explanation:
Perimeter of an Astroid = 6l ---> 6 x 7 = 42 units
Area of an Astroid = (3 x pi x a^2)/8 = 57.73 square units
I believe the X numbers are divided by 2, to get the Y numbers. So the blank X box is 1 and the other is 12.
The right answer is
0.627
You could answer this question easily by applying synthetic division:
_______________
-5 / 4 14 -9
-20 30

4 -6 21
Lots of red herrings in this question! The beacon is circular, so you need to find the area of a circle with a diameter of 36 inches.
Area of a circle = pi x radius^2
remember radius is half the diameter!
