Answer:
B. Square
Step-by-step explanation:
Finding the side lengths :
<u>Side 1</u>
⇒ d₁ = √(-4 - 0)² + (8 - 8)²
⇒ d₁ = √16
⇒ d₁ = 4
=============================================================
<u>Side 2</u>
⇒ d₂ = √(-4 + 4)² + (8 - 4)²
⇒ d₂ = √16
⇒ d₂ = 4
===========================================================
<u>Side 3</u>
⇒ d₃ = √(-4 - 0)² + (4 - 4)²
⇒ d₃ = √16
⇒ d₃ = 4
============================================================
<u>Side 4</u>
⇒ d₄ = √(0 - 0)² + (8 - 4)²
⇒ d₄ = √16
⇒ d₄ = 4
As all sides of the figure are equal, and it creates 4 right angles, it is a square.
Answer:
The above expression shows that ratios of the areas of the circles are equal to the square of the ratio of their radii.
Step-by-step explanation:
Radius of first circle = 9 inches
Area of first circle =
Area of first circle = 9 × 9 × π = 81 π
Now, since the radius is multiplied by 2/3 for from a new circle.
∴ Radius of the second circle =
Area of second circle =
Area of second circle = 6 × 6 × π = 36 π
Now,
∵ = 9 inches and
= 6 inches
The above expression shows that ratios of the areas of the circles are equal to the square of the ratio of their radii. i.e.,
