Answer:

1. Area = 78.5 (using 3.14 as pi)

2. Circumference = 31.4 (using 3.14 as pi)

Step-by-step explanation:

Area=r^2\pi \\Circumference = 2r\pi

The radius is equal to 5 yd. We can use this information to find the are and the circumference. Let's find the area first!

A=(5)^2\pi\\A=25\pi \\A= 78.5

So, the area of the circle is 78.5 yd²

Now, let's find the circumference!

C=2(5)\pi \\C=10\pi \\C= 31.4

So, the circumference of the circle is 31.4 yd

Is the sum of the areas of two smaller squares equal to the area of a large square if the side lengths of the squares are 8 feet
Ivanshal [37]

No, the sum of the areas of two smaller squares is not equal to the

area of a large square

Step-by-step explanation:

To solve this problem let us do these steps

1. Find the area of the larger square

2. Find the area of the two smaller squares

3. Add the areas of the two smaller squares

4. Compare between the sum of the areas of the 2 smaller squares

   and the area of the larger square

The area of a square is s²

The length of the side of the larger square is 8 feet

∵ s = 8 feet

∴ Area of the larger square = (8)² = 64 feet²

The lengths of the sides of the smaller squares are 5 feet and 3 feet

∵ s = 5 feet

∴ The area of one of the smaller square = (5)² = 25 feet²

∵ s = 3 feet

∴ The area of the other smaller square = (3)² = 9 feet²

The sum of the areas of the two smaller squares = 25 + 9 = 34 feet²

∵ The area of the larger square is 64 feet²

∵ The sum of the areas of the two smaller squares is 34 feet²

∵ 64 ≠ 34

∴ The sum of the areas of two smaller squares is not equal to the

   area of a large square

<em>No, the sum of the areas of two smaller squares is not equal to the</em>

<em>area of a large square</em>
