The area of the square is 100 square centimeters. What is the area of the circle?
swat32

Answer:

  • Since the question is incomplete, see the figure attached and the explanation below.

Explanation:

Since the figure is missing, I enclose the figure of a square inscribed in a circle.

Since the <em>area of a square</em> is the side length squared, you can determine the side length:

  • Area = (side length)²
  • 100 cm² = (side lenght)²

        side\text{ }length=\sqrt{100cm^2}=10cm

From the side length, you can find the diagonal of the square, which is equal to the diameter of the circle, using the Pythagorean theorem:

  • diagonal² = (10cm)² + (10cm)² = 2 × (10cm)²

         diagonal=\sqrt{2\times (10cm)^2}\\ \\ diagonal=10\sqrt{2} cm

The area of the circle is π (radius)².

  • radius = diameter/2 = diagonal/2

        area= \pi \times (5\sqrt{2}cm)^2=50\pi cm^2

HELP ME PLEASEEE DJSUS JDIDJSJDHOSSJEJDKDHKS
Elza [17]

Answer:

(8, 20)

Step-by-step explanation:

Let's input each values of the ordered pair given as options to see which one satisfy the equation y = 16 + 0.5x

==>Option 1: (0, 18)

18 = 16 + 0.5(0)

18 = 16 + 0

18 ≠ 0

Option 1 is incorrect.

==>Option 2: (5, 19.5)

19.5 = 16 + 0.5(5)

19.5 = 16 + 2.5

19.5 ≠ 18.5

Incorrect.

==>Option 3: (8, 20)

20 = 16 + 0.5(8)

20 = 16 + 4

20 = 20

CORRECT

==>Option 4: (10, 21.5)

21.5 = 16 + 0.5(10)

21.5 = 16 + 5

21.5 ≠ 21

Incorrect.

The answer is (8, 20)
