Circumference, C = 2\pir. Find the radius using this formula then use it to find the area with A = \pir^{2}.

OR use the formula A = \frac{C ^{2} }{4\pi }

Hope it helps. mark as brainliest if it does...

Find the area enclosed by the figure. Use 3.14 for π. (The figure is not to scale).<br><br>​
gtnhenbr [62]

Answer:

97.27 yd²

Step-by-step explanation:

First let's find the area of the right triangle on the left side. To do that, multiply 6x5, then divide the product by 2, since a right triangle is half a rectangle.

6x5=30

30/2=15

Area of triangle=15 yd²

Find area of the middle rectangle. So multiply the length by the width.

9x6=54

Area of rectangle=54 yd²

Find area of the half circle. Formula for area of circle is A=\pi r^{2}. Pi is about 3.14, and radius (r) is 3. Radius is half of the diameter of circle, and the 6 on the left says the diameter of circle.

\pix3^{2}≈28.27

Area of circle is about 28.27 yd²

Add up the three areas.

15+54+28.27=97.27

andrew-mc [135]

Answer:

A ≈ 12.57

Step-by-step explanation:

You have to take the formula: A = πr^2

1) Plug in what you know: A = π•2^2

2) π = 3.14 and 2^2 = 4

3) Multiply to get: 12.56637

4) Round

A ≈ 12.57

What is the factorization of 729x^15 + 1000?
Tcecarenko [31]

Answer:

729x¹⁵ + 1000

This is a case of a sum of cubes.

729 is the cube of 9

1000 is the cube of 10

x¹⁵ is the cube of x⁵

A sum of perfect cubes can be factored into 

(a + b) (a² - ab + b²)

(9x⁵+ 10) ((9x⁵)²-(9x⁵)(10) + 10²)

(9x⁵ + 10) (81x¹⁰ - 90x⁵ + 100) THIS IS THE FACTORIZATION

9x⁵ (81x¹⁰ - 90x⁵ + 100) + 10(81x¹⁰ - 90x⁵ + 100)

729x¹⁵ - 810x¹⁰ + 900x⁵ + 810x¹⁰ - 900x⁵ + 1000

729x¹⁵ - 810x¹⁰ + 810x¹⁰ + 900x⁵ - 900x⁵ + 1000

729x¹⁵ + 1000
